Gen4 HVLP20 700V 53A

The Sevcon HVLP (High Voltage Low Power) provides a highly adaptable solution for motor control applications. Using technologies based on the ever-popular Sevcon Gen4 range, the HVLP is either air or liquid-cooled. The liquid-cooled HVLP20 variant runs at up to 700V input and can provide a peak current output of 53A. The unit supports regenerative braking to reduce power consumption. A fully isolated logic and IO circuit allows for total separation of the high and low power system buses to improve safety and reliability. High voltage power connections are sealed with a protective cover and cable glands to maximize IP protection and touch safety.

Recommended Applications:

The HVLP range of motor controllers are:

  • Ideal for driving agricultural implement systems
  • Torque slave operating mode.


The HVLP supports configuration, calibration, control and status monitoring over a CAN bus using the industry-standard CANopen protocol. In order to support a wide range of applications, the unit is able to be configured as either an NMT master or slave device.

HVLP controllers can be configured to support limited compatibility with a J1939 bus.

Sevcons propitiatory "H" and "I" protocols can be used to drive and monitor IO and motor demands.

To take full advantage of the features of CAN communication on a Sevcon product, an IXXAT CAN to USB device with Sevcon DVT Software subscription will be required.

Ingress Protection:

The Sevcon HVLP range is IP66 rated, providing total protection against dust ingress and protection against water ingress during high powered pressure washing.

Motor Support:

The HVLP range provides support for the following motor types:

  • PMAC
  • Induction machine

Encoder Support:

The HVLP range provides support for the following sensor types:

  • AB
  • UVW
  • Sin/Cos
  • Resolver


Power connections are made through M10 terminal posts. This includes the DC link from a battery or other source and 3-phase output to the motor.

Signal connections are made through a 48-Way CNC connector. Signal connections include:

  • 1x Encoder connection (power supply and signal connections)
  • 2x CAN bus connection (termination available)
  • Up to 6x Configurable digital inputs (3 shared with UVW encoder input)
  • Up to 4x Configurable analogue inputs (2 shared with sin/cos encoder input)
  • 2x Configurable contactor driver outputs
  • 1x Thermistor input
  • 5V and 10V power supply outputs rated for 200mA supply each
