LPQ350 Series Data Sheet

Logic Control

Power fail

TTL logic signal goes high 50 - 150 msec after 5 V output. It goes low at least 4 msec before loss of regulation

Remote on/off

Requires an external contact (N.O or N.C) to inhibit outputs

DC-OK

TTL logic goes high 50 - 150 msec after 5 V output. It goes low when there is loss of regulation

Remote sense

Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Reverse connection

protected

1. Peak current lasting < 30 seconds with a maximum 10% duty cycle.

2. At 25 °C including initial tolerance, line voltage, load currents and output voltages adjusted to factory settings.

3. Peak-to-peak with 20 MHz bandwidth and 10 μF in parallel with a 0.1 μF capacitor at rated line voltage and load ranges.

4. 4th output 3.3 - 24 V factory set at 5 V.

5. * Minimum load required when the output is set below 5 volts.

6. If optional CF or CEF fans are not used, 30CFM forced air cooling needs to be provided and is required through the length of the power supply.

Not convection rated.

7. Remote inhibit resets OVP latch

Note: -CF suffix added to the model number indicates cover with fan,

-CEF suffix added to model number indicates end-mounted fan chassis.
