B&B Electronics DP-660 user manual Input Specifications, Output Specifications

Introductions

The DP-660 is a dual output, DIN-Rail mounted, 65 watts switching power supply. It has over voltage protection in main output and over load latch off mode protection on all output.

1.0Input Specifications

1.1Input voltage

The range of input voltage is from 85VAC to 270VAC

1.2Input Frequency

The range of input frequency is from 47Hz to 63Hz.

1.3Input current

The maximum input current is 2A at 115VAC or 1A at 230VAC.

1.4Inrush current

The inrush current will not exceed 60A at 115VAC input or 30A at 230VAC input, cold start, 25deg. C.

2.0Output Specifications

2.1Load range

Output	Min. load	Rated load	Peak load	Voltage accuracy
+24V	0A	2.5A	6A	23.76V to 24.24V
+5V	0a	0.5A		4.75V to 5.25V

At Factory, all outputs in 60% rated load conditions, the +24V output is set to between 23.76V and 24.24V and 5V is checked to be within the specified voltage accuracy range.

Peak load can test for 10 sec. Typical when other output at rated load, AC input at 115VAC.

2.2Ripple and noise

the peak-to-peak ripple and noise for each output is less then 1% of output voltage at rated load. Measuring is done by 15MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor.

2.3Line regulation

the line regulation for each output is less then +/- 1% while measuring at
