High Current Bidirectional DC Hire Units

Do you have an upcoming short circuit test? Are you looking for a battery cycler or emulator for short term hybrid vehicle testing? Perhaps you're struggling to get capital expenditure approved for a high current bidirectional power system? Then we have the perfect solution.

Our rental range has continued to expand, with 2x bidirectional G5-RSS-HC units added. Each high current module has DC source and sink nominals of 80V/±1352A/36kW, with master/slave configurations up to 80V/±2704A/72kW possible. This is in addition to our high voltage modules up to 1500V/162kW.

Each power dense module has an extensive feature set which includes programmable PID parameters and an inbuilt 8 channel recording scope. Adjustable power and resistance limits are provided. Analogue, ethernet, USB and a high-speed 1kHz CAN interface are standard with each system.

2x 36kW/80V G5-RSS-HC Cabinet IntegrationG5-RSS: Key Rental System Features

  • Sink/Source Currents up to 2704A
  • Two Current Ranges for High Accuracy
  • Programmable Ripple up to 10kHz
  • Ultra-Fast Dynamic Behaviour
  • Function Generator & Application GUIs

The G5-RSS-HC's ultra-fast dynamics with switchable capacitance allows for accurate simulation of batteries and capacitors. A current step between 90% sourcing to 90% sinking can be as quick as 50µs, enabling high speed drives to be supplied.

A selection of application GUIs are provided with each unit for battery emulation/cycling, electric drive testing and photovoltaic simulation. An embedded function generator allows almost any complex DC waveform to be implemented. Parametric programming is possible, where instead of the time axis an input variable (VIN, IIN or PIN) can be selected.

Besides our new bidirectional modules we also provide a selection of rental DC and AC sources, as well as both DC and AC electronic loads. High voltage and high current models are both available. The full rental selection is available to view on our website.
