Programmable electronic AC/DC loads » ELP/ACP series

VOLTAGE: UP TO 480VRMS | CURRENT: UP TO 900ARMS | POWER: UP TO 180kV

ELP/ACP

The ELP/ACP series are electronic loads suitable for both alternating current (AC) and direct current (DC) applications. These devices are capable of measuring a variety of parameters, including voltage, current, power, frequency, crest factor, power factor, and harmonics. Additionally, they support different operating modes such as Constant Current (CC), Constant Voltage (CV), Constant Power (CP), and Constant Resistance (CR). For three-phase applications, three individual units with the same ratings can be configured in either Delta (Δ) or Star (Y) connections. This is done via the Master/Slave interface, which allows for precise tuning and synchronization of the devices.

Standard interfaces:Operation via front, analogue
Optional interfaces:GPIB, RS232, USB, Ethernet LAN

  • AC / DC Load with CC, Linear CC, CR, CV, CP and Rectifier Load Modes
  • Frequency range: DC, 40 – 440Hz
  • Crest factor adjustable range: 1.4 – 5.0
  • Adjustable range of the power factor (PF): 0~1 leading or（-1~0）trailing
  • Optional interface: GPIB, RS232, USB, LAN.
  • Measuring the trigger or break time of the fuse and the circuit breaker.
  • Can be controlled by an external voltage for CC, Linear CC, CR, CP, CV modes.
  • Perform short-circuit simulation (short-circuit time can be set), OCP, OPP
  • Eight units parallel up to 540000W and three phases - A or Y connection can be synchronized through a master unit.
  • Supports SCR / TRIAC current phase modulation waveforms, 90 degree trailing and leading edge
  • Supports the inrush current of the power supply at startup and the overvoltage current test. If the load is suddenly plugged in (hot plug-in).
  • Built-in modes include UPS efficiency, PV inverter efficiency, UPS backup time, battery discharge time, UPS transfer time, fuse/circuit 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/circuit breaker and AC power short circuit, OCP, OPP test
  • Support load-on start; first set Load ON to support load-on start, inverter or uninterruptible power supply will directly switch on with the set load current to check whether the starter is stable when the inverter is connected.
  • 150 memory slots for saving/retrieving data
  • Supports charging and discharging angle control; charging and discharging angle control, the entire range of 0-359 degrees can be set to check 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
  • Supports positive half-cycle or negative half-cycle load; used to verify that the inverter output voltage remains stable when the actual device has only positive half-cycle or negative half-cycle load current.
  • Four measured values can be displayed V/A/W meter, display of 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 selection of computer interfaces.
