BorgWarner High Voltage Low Power Inverter

A new range of low power AC motor controllers/inverters designed primarily for ancillary control of pumps and fans on hybrid and electric buses, agricultural implements, tractors and other high voltage vehicles.

There are two models in the range, which cover both liquid cooled and air cooled designs.

  • Configurable as a vehicle control master (including pump and generator control) or as a motor control slave
  • High Voltage Interlock (HVIL)
  • 12 V or 24 V nominal supply
  • Highly configurable

Integrated I/O

HVLP includes a fully-integrated set of inputs and outputs (I/0) designed to handle a wide range of requirements. This reduces the need for additional external I/O modules or vehicle controllers and connectors.

  • All I/O protected to 40V
  • 4 analogue inputs 0 – 10V
  • 4 digital inputs
  • 2 power supplies 5 – 10V (100mA & 200mA)
  • 2 digital outputs
  • Motor temperature sensor input
  • Motor encoders supported include Resolver (programmable gain), UVW hall effect sensors, Sin/Cos sensors and incremental AB encoders
