DS5380 Low-Voltage Electronic Load Module (30 V)

PHIL testing of low-voltage and low-power auxiliary motors

The DS5380 Low-Voltage Electronic Load Module is especially designed for power hardware-in-the-loop (PHIL) testing of low-voltage and low-power auxiliary motors, which are controlled by pulse width modulation (PWM).

  • Supports onboard vehicle voltages of 12 V and 24 V
  • Suited for DC and multi-phase motor applications
  • 30 A per module, higher currents through parallel operation

The DS5380 Low-Voltage Electronic Load Module is especially designed for PHIL testing of low-voltage and low-power auxiliary motors, which are controlled by PWM. These motors are typically used in applications such as electronically controlled automatic transmissions as well as electric fuel and selective catalytic reduction (SCR) pumps. The module can work as both a current sink and current source to provide bidirectional current flow, i.e., it generates or consumes real current on ECU motor outputs.

Key Benefits

The DS5380 Low-Voltage Electronic Load Module has two independent load channels that can control a unipolar current via the module’s power output stage. The two channels can be used as a sink and source device (bidirectional current) or they can be switched in parallel to double the maximum current if a current flow in only one direction is required. This expands the range of applications beyond electric motor simulation.
