Infinity Rack Mounting & Benchtop
Linear Regulated (to 1200 watts)

AC-DC wide adjust output

SPECIFICATIONS

Input Voltage: 105-125 VAC, 50-420 Hz, single phase. (100-132 VAC, 60Hz with 30% derating.)

AC Input Current (maximum, by case size):
2U13 & 2B13: 6A
3U17 & 3B17: 15A
4U22 & 4B22: 25A

Internal Failure Protection: Provided by internal fuse or circuit breaker.

Input Undervoltage: An input of less than 105 VAC will not damage power supply.

Regulation, Ripple (in constant voltage mode): See tables: Rack Mounting Models   Benchtop Models

Regulation, Ripple (in constant current mode):
(Wide Adjust Output models)
Line Regulation: ±0.01% or 2 mA, whichever is greater.
Load Regulation:
  ≤27A models: ±0.02% or 4 mA, whichever is greater.
  ≥28A models: ±0.04% or 20 mA, whichever is greater.
Current Ripple: 0.25% rms..

Start-up Time: 75 to 150 ms.

Turn-off: Exponentially decays to zero.

Transient Response: 3 ms to return to ±1% of output setting. Maximum of ±3% output excursion following a load step change from 50% to 100%.

Short Circuit and Overload Protection: A short or overload forces the power supply into foldback protection (Single Output models), or into constant current mode (Wide Adjust Output models), with automatic recovery.

Ambient Operating Temperature: –20 to +71°C. (Derate 1%/°C above 40°C.)

Storage Temperature: –55 to +85°C.

Temperature Coefficient (after 30 minute warm-up):
Voltage mode; ±0.01%/°C (typical).
Current mode; ±0.05%/°C (typical).

Altitude Rating: Operation to 10,000 ft and storage to 40,000 ft.

Polarity: Output is floating; either positive or negative terminal may be grounded or floated up to 300 volts above ground. Optional controls and monitors are referenced to the negative terminal.

Drift, Warm-up (first 30 minutes after turn-on, @ 25°C):
Voltage mode; ±0.1% or 10 mV, whichever is greater.
Current mode (Wide Adjust models);
  ≤27A models: ±0.2% or 50 mA, whichever is greater.
  ≥28A models: ±0.3% or 75 mA, whichever is greater

Drift, Long Term (@ 25°C):
Voltage mode; ±0.03% or 10 mV, whichever is greater, over 8 hours.
Voltage mode; ±0.05% or 20 mV, whichever is greater, over 1000 hours.
Current mode, over 8 hours;
  ≤27A models: ±0.02% or 20 mA, whichever is greater.
  ≥28A models: ±0.03% or 30 mA, whichever is greater.
Current mode, over 1000 hours;
  ≤27A models: ±0.02% or 10 mA, whichever is greater.
  ≥28A models: ±0.03% or 30 mA, whichever is greater.

Remote Sensing: Provision for sensing the output voltage across the load, so that drops in the load line are compensated, is a standard feature. Compensates up to 0.5 Vdc drop per output line.

Output Voltage Adjustment: Screwdriver accessible through the rear panel.

Cooling: Forced-air cooled; air enters front of power supply and exits from rear cover.

Mounting: Rack Mounting models are designed expressly for mounting in standard 19" wide RETMA cabinet racks. Benchtop models rest on four rubber feet. Note: Slides or rear support brackets required for case size 4U22.
