PowerGate ‘H’ HVAC Bypass Controller

PowerGate ‘H’ Series HVAC Controllers offer the simplicity and functionality of an HVAC bypass controller and the high specification, performance and reliability of the Mitsubishi Electric FR-F800 VFD. The ‘Slimline’ enclosure is ideal for mounting in areas where space is limited. PowerGate ‘H’ is fully compatible with earlier generations of Mitsubishi Electric controllers and offers significant product advantages that allow it to meet the requirements of the most demanding applications.

PowerGate H

3 Contactor Bypass System
PowerGate H uses a 3rd bypass contactor to ensure that the drive is completely disconnected from the circuit when used in bypass mode, making it simple to remove the drive for service.

Anti-Windmill Feature (coasting motor restart)
The drive will detect a motor already spinning in either direction on start-up, and ensure a smooth start-up every time.

65kA Short Circuit Rating
Controllers use coordinated contactors to ensure that they can safely be installed in areas served by large supply transformers (drives have a 100kA withstand rating).

Broken Belt Detection (load memory system)
The new ‘load memory’ system detects any sudden changes in load, such as a broken belt or a clogged pump.

Broken Belt Detection

Plenum Rating
Plenum rating ensures that the controller can be used in HVAC plenums without risks caused by toxic smoke.

Dual Independent PID Control Loops
The second PID loop means that the motor speed can be controlled to maintain pressure or temperature while the position of a damper vane or valve is adjusted.

Dual PID Loop

Real-Time Clock Feature (S4 option)
Using the FR-LU08 alphanumeric display, real-time clock capability allows the time-stamping of trip messages as well as time-based operation using the internal PLC of the drive.

Motor Flux Control System
Motor load is intelligently monitored by the drive and output voltage is adjusted to match, improving efficiency and reducing motor heat and mechanical noise.

IPM Motor Compatibility
PowerGate H can be used either with conventional induction motors or with the latest generation of IPM (Internal Permanent Magnet) motors. A dedicated set-up routine ensures quick and simple commissioning.
