NCR S26 manual Table A-2 -Watt Power Supply Output Requirements

Output Requirements

Output Requirements

The following represent the output requirements of the 420-watt power supply:

∙Ripple and noise bandwidth is from DC to 20 MHz.

∙+12V should provide 15 A surge current for the first 10 seconds after power on, and this regulation should be within ±10%.

∙Total power consumption is 420 watts.

The table below shows the 420-watt power supply output requirements (measured at output power connector).
