POWER SUPPLY TESTS
Disconnect the batteries and make sure that the leads are suitably insulated to avoid a short
condition.
Disconnect the panel supply leads marked 28 V d.c. supply OUT.
Connect the a.c. mains voltage to the terminal block on the switch mode power supply and
perform the following tests.
1.
Check that the voltage at the +28 V d.c. supply output terminals is 28 ± 5V d.c. and
the polarity is correct.
2.
Check that the batteries are disconnected.
Check that the voltage at the BAT output terminals is 27.6 ± 0.2 V d.c.. and that it
drops to 26 V d.c. on full charge.
3.
Make sure that the a.c. mains and batteries are disconnected.
4.
Reconnect the cables in the 28 V output terminals observing the correct polarity of the
supply is maintained.
