Product Detail

General

The specification defines the performance characteristics of a 90 W, SINGLEOutputlevelswitching power supply for  IT   . The power supply has designed highly reliable and meet international safety and radiation requirements.

1.0Input Characteristics

1.1 Input voltage range and frequency

Rated voltage: 100-240VAC

Voltage variation range: 90-264VAC

Rated frequency: 50-60Hz

Frequency change range: 47-63Hz

1.2Input Current

At low line AC and full load, the maximum input current is 2.5A

1.3Input protection

When the AC input voltage has surges and abnormal conditions, the 5A fuse will protect the power supply

1.4Input surge current

At 25°C ambient temperature, when the input is 220Vac cold state, the maximum surge current is 80A

1.5Efficiency

1.5.1 min.At nominal input voltage,maximum load and measured at end of DC cable

Under the rated input voltage and full load, the efficiency of the DC terminal is minimum

1.5.2 Active mode efficiency:

More than 89 %min of average efficiency of 25%,50%,75% and 100% load tested at 115Vac/ 230Vac.(Warm up after 30 minutes)

115Vac/ 230Vac input, the average efficiency under test 25%, 50%, 75%, 100% load conditions is 89% minimum

1.5.3 Energy efficiency

No Load Power consumption

In the case of rated input AC and output no-load, the maximum no-load loss is 0.4W

1.6Hold up time

Under the condition of rated input AC and output full load, the minimum holding time is 10ms.

2.0Output Characteristics

2.1Turn on delay

In the case of AC low voltage input and output full load, the boot delay time is up to 3S

＊Test on delay is measured from 0 voltage output to the main output regulation.

2.2DC output regulation

＊The total adjustment rate relates to the cross adjustment rate of linearity and load

＊The test condition of linear adjustment rate is 90Vac to 2640Vac

＊The test condition of load regulation is the change from the minimum load to the maximum load under the 110Vac/220Vac input condition.

2.3Ripple/noise

＊The ripple is measured from peak to peak with band width limit of 20MHZ

(By passed at the end of connector with 10uF electrolytic and 0.1uF ceramic diskcapacitor under DC output full Load, AC nominal input 25℃ambient temperature).

3.0Protection

3.1 Short protection / Over current protection

The power supply will self-protect any output to ground, And auto recovery when

abnormal circuit faults remove.

＊An output short circuit is defined as any output impedance of less than 0.1 ohms.

＊When the effective value of output impedance is less than 0.1 ohm, it is defined as output short circuit

3.2 Over voltage protection

Test methods: Short optical coupler 1Pin to GND
