OJ-DV SeriesOJ-DV is a series of Frequency Converters dedicated for ventilation applications

A series of drives dedicated for ventilation systems comprising 13 output variants (from 0.5 to 15 kW) fitted in four different enclosures to match any rooftop fan, plug fan or AHU application.

Wide ambient temperature range
Continuous operation in almost any environment from -40°C to +50°C / -40°F to +122°F. In Fire Mode, OJ DV can run for an hour in temperatures up to +70°C / +158°F.

Flexible design
By adding different modules, OJ DV are suitable for any fan system. With their installation flexibility, they can be mounted inside or outside the air flow.

BACnet ensures that information is exchanged in a standardised way between sensors, actuators, and controls in a building. Equipped with BACnet MS/TP the OJ DV can now be part of the building automization. BACnet MS/TP is running on RS485.

Energy efficient
Passive cooling allows the drives to save energy while providing reliable, highly efficient power for the ventilation system. With OJ DV, an efficiency of up to 97% can be achieved.

Plug & Play technology
Preprogrammed motor settings help maximize functionality, while the removable front cover facilitates easy access to connectors for instant system configuration.

Norms and standards
