Gold Box "Infinity" (6-Day Power Supply)

Linear Regulated Power Supplies (to 150 watts)

AC-DC wide adjust output


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

AC Input Current (maximum): 1.3A (LM6A case), 2A (LM8A case), 3A (LM10A case).

Internal Failure Protection: Provided by internal fuse.

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

Regulation, Ripple (in constant voltage mode):
See Output Specs, Case Size, Model # and Price

Regulation, Ripple (in constant current mode):
Line Regulation: ±0.01% or 2 mA, whichever is greater.
Load Regulation: ±0.01% or 2 mA, whichever is greater.
Current Ripple: 0.25% rms.

Start-up Time: 75 to 150 msec.

Turn-off: Exponentially decays to zero.

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%.

Short Circuit and Overload Protection: A short or overload forces the power supply into constant current mode, with automatic recovery.

Ambient Operating Temperature: –20 to +71°C.

Storage Temperature: –55 to +85°C.

Temperature Coefficient (after 30 minute warm-up):
Voltage mode; ±0.01%/°C (typical).
Current mode; ±0.005%/°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; ±0.03% or 5 mv, whichever is greater.
Current mode; ±0.01% or 10 ma, whichever is greater.

Drift, Long Term (@ 25°C):
Voltage mode; ±0.01%or 5mv, whichever is greater, over 8 hours.
Voltage mode; ±0.015% or 10 mv, whichever is greater, over 1000 hours.
Current mode; ±0.01% or 5 ma, whichever is greater, over 8 hours.
Current mode; ±0.02% or 10 ma, whichever is greater, over 1000 hours.

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 front panel.

Dielectric Withstand Voltage       Isolation
Input to output:     4242 Vdc      500 VAC 
Input to case:       2121 Vdc      500 VAC 
Output to case:       750 Vdc      300 VAC 

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

Mounting: Threaded mounting holes permit mounting to a chassis, cabinet wall or bracket. To mount from the power supply side of the mounting surface use Mounting Kit GB8 or GBR, or for DIN rail mounting use Mounting Kit LH35DIN or LR35DIN.
