  4 digit V / A/W Meter,display the Voltage(Vrms, Vpeak, Vmax., Vmin)、Current (Irms, Ipeak, Imax., Imin.)、Watt, Voltampere (VA)、requency、Crest Factor、Power Factor、Total Harmonic Distortion of Voltage (VTHD), Voltage Harmonic(VH)、Total Harmonic Distortion of Current(ITHD), Current Harmonic(IH)
CC, Linear CC, CR, CV, CP and AC Rectifier Load mode
Crest factor range : 1.414~5.0
Power factor(PF) range : 0~1 lead or(-1~0)lag
Built-in function test modes include UPS Efficiency, PV Inverter Efficiency, UPS Back-up time, Battery Discharge time, UPS transfer time, Fuse/Breaker Trip/Non-Trip, Short circuit , OCP, OPP test modes
Turbo mode is able to increase to 2 times the current and power of electronic load in a short period which is the most suitable for Fuse / Breaker test and short circuit, OCP, OPP test of AC power supply
Time measurement can be applied to batteries, UPS, fuses and circuit breakers and other tests
Three units parallel up to 11250W and three-phase △ or Y load connection can be synchronized control by one master unit
Frequency Range : DC, 40~440Hz
Voltage and current monitoring
Can be controlled by external voltage for CC, Linear CC, CR, CV, CP operating modes
Protection against V, I, W, and ℃
Optional interface:GPIB、RS232、USB、LAN
