SPECIFICATIONS
Input Voltage: 90-265 VAC, 49-420 Hz, single phase, or
110-350 Vdc.
208 VAC 3-phase is also available (see Options).
AC input (maximum): 8A (WL7 case), 12A (WL9 case)
DC input (maximum): 5.75A (WL7 case), 8.8A (WL9 case).
DC input may be connected without regard to polarity.
Inrush current: Cold start, (thermistor limiter) 33A peak @115 VAC (typical); 65A peak @ 230 VAC (typical).
Startup Time: 800 mS (typical).
Input Undervoltage: An input of less than 90 VAC will not damage power supply.
Power Factor:0.99 (typical) at 115 VAC, 60 Hz and full load. Complies with EN61000-3-2.
Regulation (in constant voltage mode):
Line Regulation: ±0.05% or 5 mV, whichever is greater.
Load Regulation: ±0.05% or 5 mV, whichever is greater.
Regulation, Ripple (in constant current mode):
Line Regulation: ±0.2% or 30 mA.
Load Regulation: ±0.5% or 100 mA.
Current Ripple: 0.5% rms.
Ambient Operating Temperature: 0 to +71°C.
Temperature Coefficient (after 30 minute warm-up):
Voltage mode: ±0.02%/°C (typical).
Current mode: ±0.1%/°C (typical).
Drift (voltage mode or current mode): ±0.1% (typical) over 8 hours, after 30 minute warmup.
Storage Temperature: –40 to +85°C.
Holdup Time: 20 mS minimum with full load.
Transient Response: 300 µS to return to ±1% of output setting. Maximum of ±3% output excursion following a load step change from 50% to 100%.
Efficiency: See Output Specs. (typical, at 115 VAC, with full load.)
Polarity: Output is floating and may be used in either polarity.
Remote Sensing: Compensates up to 0.5 volt drop per output line (or within the limits of the output voltage adjustment range).
Output Adjustment: Voltage and current output adjustments are located on the front. Output adjustment may also be controlled by using remotely located potentiometers.
Voltage Monitor Terminal: Permits remote monitoring of output voltage, stepped down by a ratio of 10:1 (for 3.3v to 90v models) or 100:1 (for 100v to 135v models). Accuracy is 0.5% of maximum rated output voltage.
Current Monitor Terminal: For models with greater than 10 amps output current: permits remote monitoring of output current, stepped down by a ratio of 100 mV/Amp (accuracy is 3% of maximum rated output current). For models with less than 10 amps output current: permits remote monitoring of output current, stepped down by a ratio of 1000 mV/Amp (accuracy is 3% of maximum rated output current).
Overload/Short Circuit Protection: A short or overload forces the power supply into constant current mode, with automatic recovery.
Overvoltage Protection: Latches power supply OFF, reset by momentarily removing AC input power. (Models with ‘N’ option reset automatically.)
Thermal Protection: Thermostat(s), self-resetting.
Internal Failure Protection: Provided by internal fuse.
Output Inhibit: Applying between +3 and +15 Vdc to the Inhibit terminal will disable the supply. ‘Output Enable’ is also available (see Options).
Vout OK: When the power supply’s output voltage is between -10% and +15% of the nominal output voltage, ‘Vout OK’ will be between +3 and +5Vdc(high). When the output voltage is outside the -10%, +15% window, the 'Vout OK' voltage will go low (approx 0.5 Vdc). 'Vout OK' can source 1 mA or sink up to 5 mA.
Output Indicator (DC on): Green LED.
Switching Frequency: 110 kHz (typical).
EMI: Designed to meet FCC Part 15 and EN55022, Class A.
Dielectric Withstand Voltage Isolation --------------------------------------------- Input to output: 4242 Vdc 300 Vdc Input to case: 2121 Vdc 300 Vdc Output to case: 750 Vdc 300 Vdc
Cooling: Forced-air cooled; air enters rear of power supply and exits from front cover.
