SPECIFICATIONS
WARNING: HIGH LEAKAGE CURRENT. EARTH CONNECTION ESSENTIAL BEFORE CONNECTING SUPPLY.
Input Voltage: 100-265 VAC, 49-420 Hz, single phase. AC Input, max.: 22A (1400W)
Inrush current: Cold start, (thermistor limiter) 66A peak @115 VAC (typical); 130A peak @230 VAC (typical). (Not recommended for use on ground fault protected circuits.)
Startup Time: 1 second (typical).
Input Undervoltage: An input of less than 100 VAC will not damage power supply.
Power Factor: 0.97 typical at 115 VAC, 60Hz and full load. Complies with EN61000-3-2.
Regulation (in constant voltage mode):
Output below 60A:
Line Regulation: ±0.1% or 10 mV, whichever is greater.
Load Regulation: ±0.1% or 10 mV, whichever is greater.
Output above 60A:
Line Regulation: ±0.1% or 30 mV, whichever is greater.
Load Regulation: 0.1% or 30 mV, whichever is greater.
Regulation, Ripple (in constant current mode):
Output below 60A:
Line Regulation: ±0.4% or 60mA.
Load Regulation: ±1% or 200mA.
Current Ripple: 1% rms.
Output above 60A:
Line Regulation: ±1% or 0.5A.
Load Regulation: ±2% or 2A.
Current Ripple: 2% rms.
Ambient Operating Temperature: 0 to +71°C.
Temperature Coefficient (after 30 minute warm-up):
Voltage mode; ±0.04%/°C (typical).
Current mode; ±0.2%/°C (typical).
Drift (voltage mode or current mode): ±0.2% (typical) over 8 hours, after 30 minute warmup.
Storage Temperature: –40 to +85°C.
Holdup Time: 10mS minimum with full load.
Efficiency: See output specs for Rack Mounting or Benchtop models. (Typical, at 115 VAC, with full load.)
Polarity: Output is floating and may be used in either polarity, except in programmable/wide adjust models.
Remote Sensing: Compensates up to 0.5 Vdc drop per output line (or within the limits of the output voltage adjustment range).
Output Adjustment: Voltage and current adjustments are located on the front panel.
Output Programming: The output voltage and current may be programmed from 0 to full rating by means of control voltage inputs of 0 to +10Vdc (0 to +5Vdc for models with option “C5”). Voltage mode accuracy: 0.5%. Current mode accuracy: 3% for models with greater than 10 amps output current and 4% for models with less than 10 amps output current. Accuracy percentages do not apply below 5% of output rating.
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 270v models). Accuracy is 0.5% of maximum rated output voltage.
For models with 0-5v programming option “C5”: Permits remote monitoring of output voltage, stepped down by a ratio of 10:1 (for 3.3v to 45v models) or 100:1 (for 48v to 270v 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).
For models with 0-5v programming option “C5”: For models with greater than 45 amps output current: permits remote monitoring of output current, stepped down by a ratio of 10 mV/Amp (accuracy is 5% of maximum rated output current). For models with less than 45 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).
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.*
Thermal Protection: Thermostat(s), self-resetting.*
Internal Failure Protection: Provided by internal fuse.
Switching Frequency: 110 kHz (typical).
EMI: Designed to meet FCC Part 15 and EN55022, ClassA.
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 front of power supply and exits from rear cover. Fan noise rated at 54dB for 1400w models.
Size and Weight:Case | Rough | Approx. Size | Dimensions (inches) | weight -------|------------------------------|------------- 2U18 2U x 19" panel, 19.2" deep 19 lb. ---------------------------------------------------- 2B18 2U x 17" panel, 19.2" deep 19 lb. ---------------------------------------------------- See Drawing for exact dimensions
Enable: To enable the DC output, the enable terminal must be tied to the -DC output. An open collector or contact closure can be used.
Mounting: Rack Mounting models are designed expressly for mounting in standard 19" wide RETMA cabinet racks. Benchtop models rest on four rubber feet.
*Output may drop to 0v or 1/2 of output set voltage.
