The ESM4 and ESM6 series of modular AC/DC power supplies provide quick-turn-around, cost-effective power
solutions for medical applications from 400 to 1000 watts. Low leakage currents, under 300 µA (consult factory for
leakage currents under 150 µA), combined with conformance to IEC601-1 isolation and sp acing requirements make
these products ideal power sources for applications such as blood analyzers, DNA sequencers, and MRI and CAT
scanners.
The ESM4 Series is available in 400 and 600 watt configurations, both providing up to eight outputs from 2.56" x 5"
x 10.63" (65 x 127 x 270mm) chassis. The ESM6 Series is available in 600 and 1000 watt versions, both providing
up to twelve outputs from 2.56" x 7.36" x 10.63" (65 x 187 x 270mm) packages. Five single-output and two dual-
output modules can be configured in series or parallel to provide outputs from 1.45 to 58VDC.

ESM Flexibility
Notes:
Maximum current = (I1+ I2) x .9
Use two parallel links
Notes:
Maximum voltage to chassis is 500V
Use series link
Reverse bias diodes may be required for certain
applications, eg. large capacitive loads
Notes:
Where the sensing point is remote from the
output of the power supply, to avoid spurious
noise pick-up it may be necessary to:
1 Use twisted pair sense wires.
2 Use R C as shown (R1= 100W) (R2= 10W)
(C = 22µF).
