ELZ Series Regenerative Electronic Load
The ELZ Series is a regenerative electronic load with an optional PHIL interface, for simulating any linear or non-linear AC or DC load. High power density supports 30 kVA up to 55 kVA in a single cabinet and can be paralleled up to 550 kVA; three-phase high-power systems of 1.1 MW and higher can be configured on request.Who Is the ELZ For?
Test engineers working on EV charging/V2G/V2X (including bidirectional on-board chargers and EVSEs), smart grid and utility equipment, solar inverters and ESS, burn-in testing, and UPS/PDU/DC-DC converter and battery discharge testing.Dual constant power voltage range.
Low and high voltage ranges for AC or DC, with programmable transition between them, give more current at lower voltage and higher voltage at lower current for the widest operating envelope.
Power Hardware-in-the-Loop ready.
A high-speed analog I/O interface with latency under 50µs provides fast control of frequency, voltage, current and waveshape for real-time PHIL simulation, without add-on equipment.
Full 4-quadrant AC/DC operation.
The load draws both true and apparent power bidirectionally with programmable power factor, crest factor and current waveshape, including Circuit Emulation Mode for linear and non-linear loads.
Scalable to over 1.1 MW in three-phase.
Individual cabinets (30-220kW) parallel up to 550kW; a dedicated Three-Phase Cabinet System links multiple ELZ clusters under one Controller Cabinet to deliver up to 1.155MW of synchronized power.
