There is no or wrong output
voltage
1. Check that the input fuse is not broken.
2. Check that the input voltage is within the
specified limits.
3. The power supply output may be in current
limit due to excessive output current or an
external short-circuit on the output.
•
Measure the output voltage. If shows
> 0.5 V the thyristor OVP, see section
7.2, might have trigged.
•
Disconnect the input by an external
voltage breaker.
•
Disconnect the load.
•
Connect input fuse again and measure
the output voltage. If the converter
now starts the load was too heavy or
there was a short circuit.

remove it.

If the load is too large decrease the
load or consult your Polyamp dealer.
