Option C
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.
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 10 A.
Inrush: Cold start ac current is less than 10 A at 115 Vac and
18 A at 230 Vac.
Option “C”, Cover: Limits contact with power supply interior.
Option “F”, Fan/Cover Assembly: Cover with integral ball-
bearing fan provides proper cooling to achieve full ratings at 50°C
ambient temperature.
Holdup Time: 16 ms minimum after removal of power, at
nominal line, full load.
Efficiency: 80% typical.
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.
Brownout Protection: Holds regulation to 85 Vac or 170 Vac.
OUTPUT
Adjustability: User adjustable ±5% minimum.
Line & Load Regulation: ±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.

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.
