Including Line (for 90-264Vac input change), Load (for 0-100% load change) and
temperature (0-50°C)
pk-pk, using EIAJ test method & 20MHz bandwidth
To be specified at time of ordering (chosen in ‘Output Voltage’ part of product code)
at 50% load
at 90 Vac & 100% rated output power
typical. 87% typical if Standby Supply is fully loaded
at 90 Vac, 75% load
of set voltage for 50% load change
(in 50µs within the range 25 - 100% load)
for recovery to 2% of set voltage
Auto recovery after removal of short circuit
Primary - auto recovers, secondary - cycle power to restart
Latching, need to cycle ac to restart unit.
Available if ‘no fan’ is specified, otherwise used by PSU fan.
GLOBAL SIGNALS
Remote on/off
Enable - TTL logic level low (relative to Standby 0V) enables channel 1 and fan supply
Inhibit - TTL logic level low (relative to Standby 0V) inhibits channel 1 and fan supply
Standby Supply 5V / 2A or 12V / 1A, isolated supply, not affected by remote on/off.
Power Good
Logic high indicates ac supply is good and Ch1 is within regulation
ORing FET
Allows redundant connection of power supplies with no additional diodes required.
