User questions & answers

Question: Can I use it on a gas dryer that takes 30 Amps for a split second to start? I know it runs below 8 amps once started
Answer: Its a crap shoot as to whether this meter can handle the surge current of start up. Maybe itll work once, twice, a few times. But eventually it WILL fail. Id recommend one of those add in power monitor displays with a split core transformer that is clamped around the input hot line to sense current. For example, a CrocSee CRS-022B. Much, much safer. And can sense up to 100A!
Question: can be used connecting 220 Volts at 60 Hz
Answer: Yes, this item is designed for 110-220v, 50-60hz, AC power.
Question: Can you plug space heaters into it safely
Answer: It depends, the max. wattage rating of the PN2000 is 1760w @110v or 2000w @125v (16 amps). As long as your space heater rating is lower than this, it should work. Most space heaters have a max. output of 1500W, so you should be good to go. Note: Due to the large start-up amps of space heater, though device has abilities to deal with it, we still recommend not to use the device near the max rated specs (in most cases, the true RMS Current will be around 15A) for a long time to avoid any unexpected damage or accident. And please kindly know that the inner and outer device material is fireproofing. If device is over used or exposure to excessive heat, it may cause a melt incident but it won't start a fire. Still, you need use this device carefully to avoid any fire hazard.
Question: Does it tell you how much electricity has been used in 24 hours and the cost of usage
Answer: Yes, it will give a total usage over any time period (loose power circuits will be fine, consumption kWh will be kept in memory). So you just need to let it run 24 hours and check the Electricity Consumption (EC). Regarding the cost of usage, you have to do the math. Here gives you an example: Let's say your billed KWH is 0.07 and the distribution charge is 0.04. Then the KWH charge $0.07 + distribution charge $0.04 = $0.11 per Kilowatt Hour(kWh) usage. So if your device is using total 2.4 kW-hrs(EC) per 24 hours (which is equal to 100 watts in one hour), then you are paying $0.11 per kWh * 2.4 kilowatts per day = $0.264 for each day of use. Hope this explains it better.

tDCS 4mA Max Power ApeX Type A - Professional Grade Analog System w/Meter. Full Manual Control and Unparalleled Precision.

Based on 28 reviews Check latest price

Product description

The ApeX Type A 4mA is a fully analog tDCS System with an integrated current meter and non-linear power adjustment controls. The Integrated Analog Meter allows for instantaneous, zero-latency monitoring of the current flow levels for safety and comfort. How do you know if your device is delivering less (or worse, more) power than needed without a meter? The short answer is you don’t. Here are the two main reasons why a tDCS device MUST have an integrated meter: POWER TOO LOW: tDCS depends on your device being able to cut through the natural body resistance, which varies throughout the day and is affected by your body’s PH, skin products, conditioner, hair volume, etc. If the resistance is too high a tDCS device may not be able to deliver the full amount of stimulation needed. It could be completely blocked from doing so. POWER TOO HIGH: Cheaply made software-controlled devices could malfunction (from a software bug, firmware issue, physical damage from dropping etc,) and that may cause them to send MORE power than needed. If you buy a tDCS device without a meter, you must blindly trust EVERYTHING is working exactly perfectly, that someone wrote the software perfectly the first time and that nothing goes wrong with it for however many years you use it on yourself. At ApeX, we do not take such risks. The simplicity of the Type A’s analog circuit design means the most robust tDCS System on the market. We consider tDCS a Mission Critical application, where no amount of safety is too much. The power regulation on the Type A is hardwired in, which cannot be tampered with. The very physical and chemical properties of the components used prevent the Type A from malfunctioning. With the ApeX Type A 4 mA, you will always know you are getting the stimulation you need, no more nor less. It is the only one of its kind on the market, hand-made, assembled and tested in the USA. If you are serious about tDCS, you should get the ApeX Type A tDCS System.

  • 4 mA non-linear power adjustment. Start your tDCS sessions at a low level. Raise the power level slowly without power jumps. Only when the knob is at 5 does the power rises more quickly, for comfort and safety.
  • The cleanest, purest and most accurate DC analog output. No micro controller noise, micro stepping or interference common to Chinese made, digitally controlled devices.
  • The integrated analog meter is A MUST HAVE feature for tDCS devices. It ensures the device achieved a good connection and that it is operating within range at all times.
  • All the accessories you need to get started are conveniently included, just add your own batteries and make your own saline (instructions provided).
  • 18V of power cuts through the natural body resistance more easily with easy and comfort due to a completely manual, non-linear power delivery system.

Annotation

dB is a pure counting unit: for power, dB = 10*lg(A/B). For voltage or current, dB = 20*lg(A/B). The meaning of dB can't be simpler, that is, a very large (followed by a long string of 0) or very small (a long string of zeros in front) is expressed in a short form. Such as:

X=1000000000000000 (15 zeros in total) It can be expressed as: 10lgX=150dB

X=0.000000000000001 It can be expressed as: 10lgX=-150 dB

dBm defines miliwatt (milliwatt). 0 dBm=1mw;

dBw defines watt. 0 dBW = 10lg1 W = 10lg1000 mw = 30 dBm.

By default, dB always defines the power unit, which is calculated as 10lg. Of course, in some cases, signal strength (Amplitude) can be used to describe work and power. In this case, use 20lg as the meter. This applies to both the control field and the signal processing field. For example, sometimes you can see the expression of dBmV.

Leviton 2K208-2SW Series 2000 120/208V 3P4W 200A Indoor Kit with 3 Solid Core CTs

Based on 2 reviews Check latest price

Product description

The Leviton Series 2000 line of revenue-grade meters meets all measurement and verification based opportunities - including load management and LEED rating achievement. Designed to provide a simple and effective process for accurately capturing measurements of power consumption, Series 2000 Meters are easy to specify and install for new construction and retrofits. Leviton meters utilize highly accurate current transformers for revenue-grade performance certified to ANSI standards. Competing products use current sensors that do not provide the same level of performance. Leviton offers CTs in solid and split core styles to accommodate all phases of installation and construction. Solid core CTs are ideal for new construction, when power is not live and wires can easily be threaded through the core. Split core CTs can be installed at any time without having to disconnect wire terminations, making them the optimal choice for retrofitting an existing structure. Split core CTs close securely for fast, precise installation with no need for time-consuming tie wraps and no worries about improper seating or core half separation. Both solid and split core CTs offer high quality, long term accuracy and reliability. Every Series 2000 Meter has an installer-friendly feedback feature. The red reverse phase indicator acts as an installation diagnostics tool and illuminates if a meter is improperly installed. After installation, the green duty cycle light shows that the meter is collecting electrical consumption data at the appropriate rate. All 100 and 200 Amp solid core CTs have color-coded labels to easily identify correct line/load orientation.

  • Measures kWh and demand (optional)
  • Certified to all applicable standards of ANSI C12.1
  • Equipped with both Isolated Pulse Output and RS-485 Serial Port (Modbus Native) standard for easy interface with most AMR and BAS systems
  • Utilizes revenue grade 0.3 accuracy class 0.1A secondary solid core current transformers (CTs) that conform to all applicable ANSI requirements or 1-Percent accuracy split-core CTs
  • Up to three sets of CTs per phase can be paralleled per meter
