3-4 SMPS Specifications
3-4-1 SMPS (Switching Mode Power Supply) Specification
Item Description Remark
Input Voltage
• Typical: 100V ~ 240V AC
• Min: 90V AC
• Max: 264V ac
Input Current • Max: 1.5A (When 120V)
Inrush Current Limiting
• Max: 30A at 115Vac input Voltage for a cold start at 25℃
ambient conditions
Load Regulation
• +24V ±5% @ 0~2.5A Static
• +24V +5/-10% @ 2~6.5A Dynamic
Ripple Noise • ±200mV @ 24Vdc
Short-Circuit Protection
• The power supply shall not be damaged from the condition that
between DC output and DC ground are shorted. An output short
circuit is defined as output impedance of less than 300mΩ for
greater than 1 second. The power supply will operate normally
when this condition is removed promptly within 2 seconds.
O.V.P
(Over Voltage Protection)
• 26Vdc~30Vdc
O.T.P
(Over-temperature Protection)
• The power supply will be shutdown at an over-temperature
condition. This shutdown shall be cleared by removal of this
abnormal condition and input power recycling.
