Parallel Use to Increase Output Power
Devises can be paralleled to increase the output power. The output voltage shall be adjusted
to the same value (±100mV) with the same load conditions on all devices, or the devices can
be left with the factory settings.
The ambient temperature is not allowed to 40°C.
If more than three devices are connected in parallel, a fuse or circuit breaker with a rating
of 10A is required on each output. Alternatively, a diode or redundancy module can also be
utilized.
Energize all devices at the same time. It also might be necessary to cycle the input power
(turn-off for at least five seconds), if the output was in overload or short circuits and the
required output current is higher than the current of one unit.
Restrictions
•
Keep an installation clearance of 15mm (left / right) between two devices and avoid
installing devices on top of each other.
•
Do not use devices in parallel in mounting orientations other than the standard mounting
orientation or in any other condition where a reduction of the output current is required
(e.g. altitude).
Pay attention that leakage current, EMI, inrush current will increase when using multiple
devices.
