Front Connect Rectifier — 500 / 600 Watt AC to DC
24/27V and 48/54V
Technical Specifications

AC INPUT
Voltage: 90—264VAC (tested to 300Vac)
Frequency: 47-63Hz
Peak Inrush Current: <45A
Power Factor: 0.99 typical
Efficiency: 90% typical with 230VAC input at 50-100% load
Hold-Up Time: 20mS min. at 23V / 46V threshold
Input Overcurrent: 8A Fuse in Line and Neutral

ELECTRONIC CONTROL INPUTS
Remote Inhibit: Application of a TTL High input signal referenced to
signal ground will cause the supply to shut down and an Output Low fault
alarm will be issued. (TTL High = Inhibit). Inhibit Low or open circuit enables power supply.
Remote Program: Provides about +7.5%, -30% of set point voltage
with 0 to 5V control signal. Open circuit or 4V control= no output change
PS ON: Remote Enable (need to be shorted to signal ground to turn
on power supply)- last make first break pin.

DC OUTPUT
Voltage: 21—28V or 42—56V
TEMPERATURE
Power: 500W (600W at 180-275VAC)
Normal Operation: -40 to +55˚C
Initial Accuracy at center load: ± 50mV
Low Temperature: -40˚C requires 1 minute warm-up
Ripple & Noise: 1% V P-P Measured with 20Mhz Bandwidth
Storage / Transportation: -40˚C to +85˚C
Line Regulation: Less than ±0.25%
Humidity Operating: 0% to 95% RH non-condensing
Load Regulation: ±2% max (1.0% typical) from nominal value
Storage: 0% to 95% RH non-condensing
Parallel Use: May be paralleled with other like units for increased system
output, an isolation OR-ing device included
PHYSICAL DIMENSIONS
Current Sharing: Slope program current share, (droop)
Dimensions: 1U, H38.4x W106 x D219mm max (1.51 x 4.16 x 8.61”
Temperature Coefficient: < ±0.02% per°C
max) excluding handle and output connector
ELECTRONIC ALARMS (Basic Set, others available)
AC Fail: low when AC input is out of range (activates 5ms before output
falls below 23V / 46V)
Output Low: A TTL Low signal if the output voltage falls 10% below the
actual output voltage set point (10 mA sink capability)
Over-temperature warning: TTL Low 5°C below over-temperature
shutdown
(NOTE: above signals are referenced to signal ground)
Isolated Output Low: open collector signal, isolated from both AC input
and DC output: high impedance if the output voltage falls below 10% of
its set point.
Power Supply present (shorted internally to signal ground)

Weight: 2.5 lb (1.1kg)
AGENCY COMPLIANCE
CE Marked: Low Voltage Directive only standards
Electrical safety: EN60950-1, CUL UL 60950-1
EMI (conducted): FCC Part 15, Sub-part J, class A and EN55022, class A
EMI (radiated): EN55022, class A in a rack.
Harmonics: EN 61000-3-2, Class A
EN 61000-4-3 Electromagnetic Immunity (error-free), Level 2 stand-alone
RoHS with Lead Solder Exemption

VISUAL FAULT INDICATORS
Power Good: A front panel Green “Power Good” LED will be lit if the
AC input is within the acceptable range.
Output Low: An amber summary fault front panel indicator “Fault” LED
will be lit if the output voltage falls 10% below voltage set point.
