INPUT SPECIFICATIONS Input Voltage Range Vac Vac Input Current Vin=85 6 Arms Efficiency 70 % Input Power Typical Vin= W (Pout Max, Fan Cooled) Inrush Current Vin= C 75 Apeak Fusing 8A/250VAC, Normal Blo (2) (1) DC Good signal is a 1mA conductance signal which indicates that DC output voltage is greater than 90% of nominal voltage. AC good signal is a 1mA conductance signal which indicates adequate input capacitor energy storage to provide 10msec holdup. DC output voltage will remain within regulation limits for a minimum of 10msec after AC Good signal ceases to conduct. AC Good signal is initiated approximately 2 seconds after input power is applied. (2) Overload of power supply does not cause fuse failure. Replace only with same type and rating. IM-SVQ3 1

(4) Remote sensing on the main output is accomplished by removing JP1 and JP2 from the printed circuit board and connecting the load to the +S1 and -S1 terminals found on J3. The maximum cable drop is 0.5 volts. (5) Minimum load on V2 and no load on auxiliaries. (6) Peak output current lasting less than 30 seconds with a duty cycle of < 5%. During peak current transients the outputs may IM-SVQ3 2

See derating table. - Proper air circulation is required when the unit is mounted in confined areas. - Remote on/off - J8 is a primary referenced connector located in the center of the unit. Short J8 terminals = unit off, open J8 terminals = unit on Note: This is a primary referenced circuit and requires proper agency clearances. The use of an opto isolator is recommended. IM-SVQ3 3

Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote sense connections. Good layout techniques, such as close proximity and directness, should be observed for noise immunity. *** Suitable decoupling capacitor (0.1uF, or higher) may be required at load.
