The GW Instek PEL-5000G series electronic loads have 1 channel and include 9 models with different combinations of power (4kW, 5kW, 6kW), voltage (150V / 600V / 1200V) and current (160A – 600A). With the help of the electronic loads you can check and verify the specifications of batteries as well as chargers and charging stations for electric vehicles precisely and reliably. The loads support parallel connections for the same voltage specifications and different power models. Up to 8 units can be connected in parallel, delivering a maximum power of 48 kW.
To test battery chargers, the PEL-5000G offers four special discharge modes, namely CV+ Current Limit Test Mode, CV+ Power Limit Test Mode, CC Mode and CP Mode.
When testing battery discharge, GW Instek loads have cut-off voltage, discharge time and discharge capacity (Ah) functions in CC and CP modes to meet battery testing requirements.
The variant PEL-5004G-150-400 presented here has an output of 4 kW, 150 V voltage and 400 A current.
Product features:
- Simultaneous display of 5 digital V/A/W meters on the large LCD display
- Operation modes CC, CR, CV, CP, CV + CL, CV + PL, Dynamic and short circuit
- Parallel operation for CC, CR and CP mode as well as in CV mode
- Capacitive load surge test mode to check current slew transients
- The voltmeter reading can be configured as positive (+) or negative (-) polarity
- Master-slave control with up to 7 slaves
- Optional interface: GPIB, RS232, USB, LAN
- The programmable function of the SEQ loading mode enables extremely fast step changes from 0.02 to 999000 ms in CC or CP mode
- Provides battery BMS protection test function
- Optional load current waveform generator to simulate actual battery discharge current
- Built-in test modes battery discharge, BMS, short circuit, OCP, OPP
- Turbo mode can withstand up to 1.5 times the current and electronic load for 2 seconds. This is especially useful for BMS, short circuit, OCP and OPP tests
