Electrical specs

Input

• Inrush current: 38 A max., cold start @ 25°C
• EMI filter: FCC Class B conducted and radiated CISPR 22 Class B conducted and radiated EN55022 Class B conducted and radiated VDE 0878 PT3 Class B conducted and radiated.
• leakage current: <0.5 mA @ 50/60 Hz, 264 VAC input
• Frequency: 47-440 Hz
• Efficiency: 85% typical at full load
• Power factor Safety ground: 0.99 typical

Output

• Adjustment range: ±5%
• Hold-up time: 20 ms @ 350 W load, 115 VAC nominal line at factory voltage setting
• Overvoltage protection: 20% to 35% above nominal output
• Maximum power: With cover: 350 W with 30 CFM forced air
• Supervisory outputs: 5 V @ 2A regulated, 12 V @ 1A
• Overload protection: Short circuit protection on all outputs. Case overload protected @ 115-130% above peak rating

Logic Control

• Remote on/off: Requires an external contact closure to inhibit outputs
• Remote sense: Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Reverse connection protected.
• Power failure: TTL logic signal goes high 100-500 msec after main output. It goes low at least 4 msec before loss of regulation
• DC OK: TTL logic goes high after the output is in regulation. It goes low when there is loss of regulation.
