As HVAC equipment shrinks and building automation networks get more demanding, OEMs and system integrators need a drive that keeps up—without adding installation complexity or long-term maintenance headaches. Tight mechanical rooms, evolving refrigerant standards, and a BMS that expects native connectivity all raise the bar for what a microdrive has to deliver.
The Yaskawa HV305 HVAC AC Microdrive delivers exactly that. Engineered specifically for rooftop units, data center cooling packages, air handlers, chillers, and heat pumps, it combines sustainability, flexibility, and ease of use in a package built for 10 years of maintenance-free operation.
Key Features at a Glance
- Embedded BACnet MS/TP & Modbus RTU — connects directly to the building automation network, with a wide variety of additional communication options available.
- UL/CSA compliant for A2L refrigerants — keeps pace with evolving refrigerant standards.
- 100 kA rms SCCR — short-circuit current rating built for robust electrical protection.
- Up to 30% smaller than comparable drives on the market.
- 10-year maintenance-free design — backed by an MTBF of 28 years.
- Program without power — via USB, even while the drive is still in the box.
Smarter Control at Your Fingertips
Setup and day-to-day operation are designed to be effortless:
- Removable keypad backs up and copies parameters across multiple drives.
- Intuitive keypad navigation with an easy-to-read LED display, plus optional LCD or Bluetooth keypad.
- DriveWizard® HVAC software and DriveWizard® Mobile app simplify parameter management, start-up, and troubleshooting from a smartphone or tablet.
- LED status ring gives an at-a-glance read on drive status.
- Finger-safe terminals speed up wiring — no need to remove the cover.
- Tool-free cooling fan replacement keeps maintenance fast and simple.
Compact, Flexible Installation
No two mechanical rooms are alike, and the HV305 is designed to adapt. It supports a variety of mounting methods — standard, IP20/UL Type 1, side-by-side, external heatsink, and DIN rail — so it fits the space you have, not the other way around.
