Forced-air cooling of 5 CFM is required for full output power except for

MPB125-2003 and -2003D. Air velocity is measured with power supply mounted on

0.375" (9.5mm) standoffs. Airflow direction is from the input section to

the output section. See Application Note #M3 for details.

DESCRIPTION

Remote On/Off

Standby Output

(Option R)

NOTES

Remote On/Off is a TTL-comatible signal. A logic “high” or open circuit turns the unit on. Reverse inhibit logic can be achieved

by changing the position of the J6 connector. A logic “low” inhibits all outputs except the 5V standby. At remote off, the Power

Good signal will warn the host equipment 2 milliseconds before the main output goes out of regulation. The rating of the

standby output is +5V @ 0.2 Amps. Total regulation is ±5 %. Maximum noise and ripple is 50 mV peak-to-peak @ a 20 MHz

bandwidth.

NOTE: The addition of Option “R” increases the supply width from 3.0 to 3.8 inches. Consult factory for availability.

NOTES: 1 For MPB125-2003 and -2003D, a minimum airflow of 10 CFM is required to provide the maximum current of 30A on V1. V1 current can be as high as

25A with a minimum airflow of 5 CFM.
