Programmable electronic AC/DC loads » ELP/ACP series

The ELP/ACP series is a multifunctional electronic load for AC and DC applications. They can measure various parameters such as voltage, current, power, frequency, crest factor, power factor and harmonics. They also support various operating modes such as constant current (CC), constant voltage (CV), constant power (CP) and constant resistance (CR).

Overview:

The main features of the ELP/ACP series of load are highlighted below.

• AC / DC load with CC, Linear CC, CR, CV, CP and Rectifier Load mode
• Frequency Range : DC, 40~440Hz
• Crest factor adjustable range : 1.4~5.0
• Power factor (PF) adjustable range: 0~1 lead or（-1~0）lag
• Optional interface: GPIB, RS232, USB, LAN.
• 150 set Store/Recall memory.
• Measure the fuse and circuit breaker trip or blow time.
• Measure the UPS OFF-Line transfer time (Transfer time).
• Can be controlled by external voltage for CC, Linear CC, CR, CP, CV mode.
• Perform short circuit simulation (can set the short circuit time), OCP, OPP.
• Eight units parallel up to 540000W and three-phase △ or Y load connection can be Synchronized control by one master unit.
• Supports SCR/TRIAC current phase modulation waveforms, 90 degree Trailing edge And Leading Edge.
• Over voltage warning, over current, over power, over temperature protection.
• Supports the Inrush Current of the power supply at startup and the Surge Current test. When the load is suddenly plugged in (Hot Plug-in).
• Built-in modes include UPS Efficiency, PV Inverter Efficiency, UPS Back-up time, Battery Discharge time, UPS transfer time, Fus/Breaker Trip/Non-Trip, short circuit Simulation, OCP, OPP, etc.
• Turbo mode, which can withstand up to twice the current (225A) and power (45KW) load in a short time, most suitable for Fuse/Breaker and AC power short  Circuit, OCP, OPP test.
• Support on-load boot; at first set Load ON to support on-load boot, inverter or Uninterruptible power supply is turned on directly with the set load current, used to verify Whether the starter is stable when the Inverter is connected.
• Supports the loading and unloading angle control; the loading and unloading angle Control, the full range of 0-359 degrees can be set to verify whether the Inverter output Voltage transient response is stable when the actual electrical plugging and unplugging, And whether Overshoot/Undershoot is within the allowable range.
• Support positive half-cycle or negative half-cycle loading; used to verify whether the Inverter output voltage remains stable when the actual appliance has only positive half- Cycle or negative half-cycle load current.
• Four meters can be displayed V/A/W Meter, display the Voltage (Vrms, Vpeak, Vmax.,Vmin), Current (Irms, I Peak, Imax. Imin.) Watt, Voltampere (VA), Frequency, Crest Factor, Power Factor, Total Harmonic Distortion of Voltage (VTHD), Voltage Harmonic (VH), Total Harmonic Distortion of Current (ITHD), Current Harmonic (IH) Remote Control via a choice of Computer interfaces.
