Power modules - general

Indicators

All modules have POWER ON and
proportional OUTPUT mimic LEDs

Status

ERROR LED indicators

Safety

Power modules are class 2, double
insulated and fully enclosed to prevent
exposure of live parts if a module is
removed from the rack. Each module
shuts down automatically under an
overheat condition

Efficiency

Dimmer power efficiency at least 97%
at full load. No-load loss of 3V RMS
for standard 3kW dimmers

Non-Dims

Contactors are used for Non-Dims
modules - not thyristors.

type insertion. Any 3kW dimmer
(including reporting) can fit in any
3kW crate, any 6kW in 6kW crate etc.
