|Logic Control|Logic Control|
|---|---|
|Power failure|TTL logic signal goes high 50 - 150 msec after 5 V output. It<br>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<br>when there is loss of regulation|
|Remote sense|Compensates for 0.5 V lead drop min. Will operate without<br>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. 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. 

5.  Output voltage adjustment requires a 1A load. 

Astec Connector Kit #70-841-011, includes all of the above. 

6. 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.
