Line Regulation .............. At the Sense Point, Over Full Input Range <±1%,

                                        sense leads connected.

Load Regulation ............. Output voltage droops with increasing load.

Minimum Loading........... 5% minimum on V1.

Stability .......................... Output drift <±0.2% after 20 minute warm-up.

Temp. Coefficient ........... <±0.02%/ºC, 0º - 50ºC, after 20 minute warm- up.

                                       Dynamic Response ........Less than 3% deviation with a 25% load change

                                        at 1A/µsec. Output returns to within 1% in less

                                        than 300µsec.

                                        Ripple and Noise

(PARD)........................... For all outputs, 50mV max or 1% peak-to-peak

                                        nominal, which ever is greater, DC to 20MHz

                                        bandwidth with a coaxial probe and 0.1µF/22µF

                                        capacitors at the output terminals.

Current Sharing/

Parallel N+1 Operation ... V1, V2, V3 Outputs. Droop method standard.

                                        Optional single wire design in development.

                                        Consult factory for availability.

Remote Sense................ V1, V2, V3 outputs compensate for up to 0.25V

                                        total line drop in the load cables. Outputs are

                                        internally sensed if leads are opened.

Hold-Up Time ................. Outputs remain in regulation >15msec minimum

                                        following loss of AC power at low line, full load.

Over Current/Short

Circuit Protection............ Current limit on all outputs. Automatic recovery

                                        when overload is removed.

Over Temperature

Protection....................... Internal temperature sensing. Causes all outputs

                                        to shut down. Automatic recovery.

Over/Under Shoot .......... None at turn-on or turn-off.

Under Voltage Warning ..Any output dropping below 10% of nominal

                                        triggers the power fail warning signal.

Over Voltage

Protection .......................Non-crowbar type. Any output that exceeds

                                        25% ±10% of nominal Vout will cause all outputs

                                        to latch off. Remote inhibit, enable or input

-SIGNALS, INDICATORS and CONTROLS-

Remote Enable...............Enabled by closed circuit or TTL logic 0.

                                       Disabled by open circuit or TTL logic 1.

Power Fail Warning .......Loss of input AC causes a TTL compatible signal to go low >4msec prior to any output dropping out of regulation. At AC turn-on, signal stays low until all outputs are in regulation. PF signal also triggered by an under voltage condition on any output.

LED Indicator..................Dual LEDs. Green indicates input power ON and outputs within regulation. Off or Amber  indicates input and/or output power fault.

-OPERATING ENVIRONMENT-

Operating Temperature ..0º – 50ºC ambient at full load, with specified airflow.

Cooling ...........................A minimum of 15 cfm / 400 lfm direct forward airflow required to achieve full rated power and specified MTBF. Consult factory for derating guidelines with reduced or reversed airflow.
