TABLE 2. POWER SUPPLY RATINGS AND SPECIFICATIONS
SPECIFICATION DESCRIPTION
Input Voltage Nominal: 100-120V a-c or
200-240V a-c Range: 85-265V a-c
(0 to 100% load, -10 to 65°C)
Range 110-370V d-c Polarity insensitive (0 to 100% load, -10 to 65°C) Safety
agency approval applies only to a-c input operation.
Input Source Frequency Nominal 50/60 Hz, Range 47-440 Hz. (At 440 Hz the leakage current exceeds the VDE leak-
age safety specification limit).
Input Current: (Maximum Load At
25°C with Nominal Output Voltage) 100 - 120V a-c 8.4A rms max. (7.2A rms max for the 3.3V model)
200 - 240V a-c 4.2A rms max. (3.6A rms max for the 3.3V model)
Input Protection A thyristor circuit reduces start-up surge. Units are protected against shorts by an input fuse.
Fuse value 15.0A At 250 Volts
Input Surge cold start,
interval > 30 sec (1)
100 - 120V a-c 15A typ., 30A max. first surge
200 - 240V a-c 30A typ., 60 max. first surge
Leakage Current: 0.45mA typ., 0.75mA max. at 120V a-c, 60Hz (per IEC 950 and UL1950)
0.60mA typ., 0.75mA max. at 240V a-c, 60Hz (per IEC 950 and UL1950)
Power Factor 100V a-c 0.99 typical
200V a-c 0.95 typical

terminals (0%-100% load change) 0.3%
(0.45% for 3.3V Model)
0.6%
(0.9% for 3.3V Model)
Temperature Effect (–10° to 71°C) 0.5% 1.0%
Combined Effect (envelope, Source,
Load and Temperature) ±0.9%
(±1.1% for 3.3V Model)
±1.8%
(±2.2% for 3.3V Model)
Drift (from 1/2 to 8 hours at 25°C) 0.2% 0.5%
Remote Error Sensing: Compensation up to 0.4 Volts per load wire (0.15 Volts for RCW 3.3-70K, 0.25 Volts for RCW
5-70K) (see Figure 8).
Transient Recovery
characteristic excursion ±4% maximum 50% to 100% load,
transient time >50
µ
sec
recovery time 1 ms maximum
Start-up Time 100 - 120V a-c 350 msec maximum, 280 msec typical.
200 - 240V a-c 150 msec maximum, 100 msec typical.
Output Hold-up Time 100 - 120V a-c 30 msec typical, 20 msec minimum.
200 - 240V a-c 40 msec typical, 20 msec minimum.
Overvoltage Protection When the Power Supply goes into an overvoltage condition, the output is cut OFF. To restart
(reset) the unit, it is necessary either to remove the a-c input power, wait about 40 seconds,
and then to reconnect the a-c input power, or reset using remote ON-OFF feature (see PAR.
3.3).
Remote Control ON/OFF: "High", 2.4V to 24V (or open), unit OFF- Fan Off ; "Low", 0.0V to 0.4V (or closed), unit ON.
Source current is 1.6mA maximum, sink current 1.0 mA maximum. The ±RC terminals are iso-
lated from the a-c input terminal and the DC output terminals. When remote ON/OFF is not in
use, ±RC terminals must be shorted (use shorting link supplied) for unit to operate.
Operating Temperature: -10 to 65°C (see Figure 2)
Startup Temperature -10 to -20°C (see Figure 2)
Storage Temperature: -30°C to +75°C
