SPECIFICATIONS: ALL MODELS

INPUT

AC Input: 90-264 Vac continuous range, 47 to 63 Hz. Internally fused for 15 A.

Power Factor: 0.99 typical at full load. Meets EN61000-3-2.

Inrush: Cold start AC current is less than 50 A at 115 Vac and 100 A at 230 Vac. Limited by

thermistor.

Brownout Protection: Holds regulation to 85 Vac.

Holdup Time: 20 ms minimum after removal of power at full load.

Efficiency: 75% typical.

AC Power Fail: Provides TTL “0” 5 ms before output voltage goes out of regulation band

upon loss of AC power.

OUTPUT

Adjustability: Outputs #1 and 2 user adjustable ±5% minimum. Output #3 tracks #2; initial

accuracy ±4%. Output #4 user adjustable ±5% minimum, or +5% only if voltage is 5.2 V.

Line & Load Reg: Outputs #1, 2, and 4 hold ±1% over AC input range and 0 to 100% load

change. Output #3 requires 20% minimum load on outputs #2 and 3 to hold ±4%.

Ripple & Noise: Less than 1% p-p or 100 mV, whichever is greater.

Remote Sense (Outputs #1 and 2): Compensates for 250 mV total line drop. Open sense lead

protection. (See Redundancy, below.)

Temperature Coefficient (Outputs #1, 2, and 4): 0.02% per degree C.

Stability: 0.1% over 8 hours after 30 minutes warm-up.

Transient Response (Outputs #1, 2, and 4): Output voltage returns to within 1% in less than

500 µs for a 50% load change. Peak transient does not exceed 5%.

Overload Protection: All outputs are protected against overload and short circuit. Automatic

recovery upon removal of fault.

Overvoltage Protection (Outputs #1 and 2): Protects load against power supply induced over

voltage. Trip point is factory set so that output voltage cannot exceed 136% of nominal.

Peak Output Current: Dual current ratings define continuous and peak currents. The peak

current shown can be delivered for a maximum period of 30 seconds.

Remote Inhibit: Contact closure to the negative sense line or a TTL level “0” turns off DC

outputs.

DC Power Good: Provides a TTL “1” when output #1 is above 4.6 V nominal.

Redundancy: External OR-ing diodes and forced current sharing on output #1 provide “N+1”

capability. Remote Sense (+S) compensates for additional 0.6 V diode voltage drop. When

the current sharing terminal is connected between units, current sharing remains within

10% of the unit’s full output current rating.

ENVIRONMENTAL

Thermal Protection: Shuts down power supply if overheated. Automatic recovery.

Temperature Range: 0° to 50° C at full ratings.

Safety Agencies: Most models are approved to UL1950; CSA 22.2 #234; IEC 950 and TÜV

EN60950, Class 1 SELV., CE 72/23/EEC/93/68EEC (low voltage directive)..

Conducted RFI: Meets FCC Part 15, Subpart J, Class A; EN55022 Class B; CISPR 22 Class B.
