The SD811 Power Supply Module provides 24V d.c. at 2.5A
and the SD812 Power Supply Module provides 24V d.c. at
5.0A.
The SD811(SD812) is a switch-mode power supply unit
converting main voltage to 24 Volts d.c. This power supply
can be utilized for non-redundant and redundant applications
and does not require additional load-sharing control
equipment or diode voting units.
Two or more power supply devices can be connected in
parallel. No special efforts are included to get the paralleled
devices sharing the load equally. Connecting units in parallel
can be used for increasing the power output or to get n+1
redundancy.
Normal function, DCOK, is indicated by a green Light Emitting Diode (LED).
Status Signal, DCOK terminal, Power Good = active high; 24V source with a series resistance = 270
ohms, signal return = 0V
