OUTPUT
Adjustability:
Outputs #1 and 2, and 4 factory adjusted to
nominal ±0.2%. Output #3 tracks #2; initial accuracy ±3%.
Line & Load Reg:
Outputs #1, 2, and 4 hold ±2% (with local
sense) over dc input range and 0 to 100% load change
(preprogrammed slope). Output #3 requires 20% minimum load
on outputs #2 and 3 to hold ±5%.
Ripple & Noise:
1% p-p or 100 mV, whichever is greater.
Remote Sense (Output #1):
Compensates for 250 mV total line
drop. Preprogrammed slope remains under ±3% worst case.
Open sense lead protection.
Temperature Coefficient (Outputs #1, 2, and 4):
0.03% 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
(measured with rise time and fall time of 200 µs). 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.
Redundancy:
Built-in OR-ing diodes, slope program current
sharing on all outputs, and self aligning connector provide “hot
swap” and “N+1” capabilities. Current sharing remains within 10%
of the unit’s full output rating while units are in thermal equilibrium.
Remote Enable:
Contact closure to common turns on dc
outputs (recessed pin for “make last, break first” connection).
Dc Power Good:
Provides a TTL “1” open collector when
output #1 is above 4.6 V nominal.
Reverse Voltage:
Protected against reverse voltage up to
supply current rating.
