SPECIFICATIONS:
INPUT
Ac Input: 90-132 Vac/180-264 Vac, 47 to 63 Hz. User selectable.
See option “A” for automatic line selection. Internally fused for 12 A.
Inrush:
Cold start ac current is less than 80 A at 115 Vac and 20
A at 230 Vac. Limited by thermistor.
Holdup Time:
16 ms minimum after removal of power, at
nominal line, full load.
Efficiency:
80% typical.
Brownout Protection:
Holds regulation to 85 Vac or 170 Vac.
Cooling:
30 cfm required to achieve full ratings.
Output Isolation:
Isolated from ground 50 Vdc.
OPTIONS:
Option “A”, Ac Auto-Range:
Automatically selects proper ac
line voltage range to enable power operation at either 115 or 230
Vac without user intervention.
Option “F”, Fan/Cover Assembly:
Cover with intergal ball-
bearing fan provides proper cooling to achieve full ratings at 50°C
ambient temperature.
Option “P”, Ac Power Fail:
Provides TTL “0” 5 ms before
output voltage goes out of regulation band upon loss of ac power.
VMEbus compatible, provides 48 mA sink current capability. Not
available if option “G” is selected.
Option “V”, Fan/Cover Assembly:
Low profile, end venting
cover with integral ball-bearing fan.

Adjustability:
User adjustable ±5% minimum.
Line & Load Reg:
±1% over ac input range and 0 to 100% load
change. Output #1 requires minimum load of 10%.
Ripple & Noise:
Less than 1% p-p or 100 mV, whichever is
greater.
Remote Sense (Output #1):
Compensates for 250 mV total line
drop. Open sense lead protection.
Temperature Coefficient:
0.02% per degree C.
Stability:
0.1% over 8 hours after 30 minutes warm-up.
Transient Response (Output #1):
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 (Output #1):
Protects load against
power supply induced overvoltage. Trip point is factory set so
that output voltage cannot exceed 136% of nominal.
Remote Inhibit:
Contact closure to the negative sense line
drops output power to nominal zero.
Reverse Voltage:
Protected against reverse voltage up to
supply current rating.
ENVIRONMENTAL
Thermal Protection:
Shuts down power supply if overheated.
Automatic recovery.
Temperature Range:
0° to 50°C at full ratings. Derate to half
power at 70°C.
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.
