DESCRIPTION
SPECIFICATION

The WT300E series digital power analyzer provides extremely low current measurement capability down to 50 micro-Amps, and a maximum of up to 26 Amps RMS. This instrument is ideal for engineers performing stand-by power measurements, Energy Star®, SPECpower and IEC62301 / EN50564 testing, battery charger and other low-level power measurements. The WT310EH allows 40 Arms to be directly connected to the input without the requirement to use current clamps or current sensors. This not only provides more precise measurement but also saves on investment costs. The wide current ranges are from 1 A to 40 A and voltage ranges are from 15 V to 600 V. Users can use it to evaluate special waveform driven devices such as, IH cookers and heaters.

Basic power measurement accuracy (50/60 Hz) : 0.1% of reading + 0.05% of range
Influence of power factor : When power factor ( ) = 0 (S: apparent power) ±0.1% of S for 45 Hz ≤ f ≤ 66 Hz
Frequency bandwidth : DC, 0.1 Hz to 100 kHz (WT310EH DC, 0.1 Hz to 20 kHz)
Direct input Current range : 6 ranges/0.5 to 20 A
External current input : EX1: 2.5/5/10 [V] & EX2: 50 m/100 m/200 m/500 m/1/2 [V] (OP.)
Expansion of effective input range for voltage & current (CF = 6A) : 2% to 260%*1
Expansion of maximum displaying value for voltage & current (CF = 6A) : 2% to 280%*2
Frequency measurement : 2 channels (voltage and current)
Sampling rate : Approximately 100 kS/s
Data Update rate : 100 m/250 m/500 m/1/2/5/10/20 sec, Auto

The Universal Relay Test Set and Commissioning – Omicron CMC356 Essential Package

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
