Overview
We design and supply motor controllers for compressor-based HVAC systems – from room and packaged air conditioners to mobile and DC-powered cooling. Versa Drives’ compressor controllers cover both AC induction compressors and high-efficiency PMSM / BLDC compressors, with sensorless control, built-in protections and compliance to IEC 61800 standards.
For OEMs, these platforms can be adapted for new capacities, voltage ranges and control interfaces without starting from a blank sheet every time.
Key Solution Areas
- Residential and light-commercial air conditioners (fixed and inverter-type)
- Compact DC compressors for mobile / off-grid HVAC
- Telecom, cabin and cold-box cooling using 12 / 24 / 48 V DC compressors
- Custom HVAC cooling blocks where only the compressor and controller are supplied
Platform Capabilities – At a Glance
Motor types
- AC induction compressors (V/F control)
- 3-phase PMSM / BLDC compressors (sensorless vector control)
Power range
- ~0.5 kW to ~1.8 kW (extendable with platform customisation)
Supply options
- Single-phase 168–264 V AC (for AC compressors)
- 12 / 24 / 48 V DC bus for PMSM / BLDC compressors
Control features
- Sensorless vector control for PMSM / BLDC
- Fixed and variable speed configurations
- Analog speed command (0–5 V) and digital I/O options
Protection & reliability
- Under-voltage, over-voltage, over-current, overload and over-temperature protection
- Locked-rotor and low-speed detection where applicable
- Designs aligned to IEC 61800-3 and IEC 61800-5-1, with IP44–IP54 options based on enclosure
Integration options
- Thermistor inputs for compressor temperature
- Relay outputs for condenser fan / blower control
- Optional isolated serial communication (e.g., RS-232) for OEM diagnostics
Current Products on this Platform
1) AC Compressor Drive – 230 V AC
- Single-phase 168–264 V AC input with three-phase compressor output.
- Linear V/F control for 1.5–1.8 kW compressor motors.
- Integrated protections (over-voltage, under-voltage, over-current, motor overload, over-temperature).
- Thermistor inputs and relay outputs to coordinate compressor and blower operation.
- Ideal for room and packaged AC OEMs needing a compact, ready-to-integrate compressor drive.

2) DC Compressor Controllers – 12 / 24 / 48 V DC PMSM
- 3-phase PMSM / BLDC compressor controllers for low-voltage DC systems.
- Voltage options:
- 12 V DC (10–16 V operating range, ~500 W PMSM compressor)
- 24 V DC (20–30 V operating range, ~500 W PMSM compressor)
- 48 V DC (37–57 V DC bus for BLDC / PMSM compressor drives)
- Sensorless PMSM control with >90% drive efficiency for 12 V and 24 V variants.
- Built-in protections: under-voltage, over-voltage, short circuit / over-current, overload, locked rotor, over-temperature.
- IP44-rated designs suitable for harsh mobile environments (12 V and 24 V variants).
- Suitable for mobile and off-grid HVAC, small cold rooms, vehicle cabin cooling and telecom cooling boxes.
Note: 12 V & 24 V page exists; 48 V can be part of this family or a separate page later.
Why OEMs Work with Versa Drives for HVAC & Compressors
- Experience in both AC and DC compressor control, including PMSM / BLDC compressors.
- Deep motor-control expertise – the same team that developed Superfan’s ultra-efficient BLDC platforms works on these controllers.
- Ability to customise firmware (speed profiles, soft-start behaviour, protection logic) for your compressor and refrigerant system.
- Proven designs aligned to IEC 61800-3 / 61800-5-1 with robust protections for demanding duty cycles.
