The unit must be powered up into the recommended minimum loads to
ensure the outputs come up.
Combined maximum output power for Aux. 1, 2 and 3 is 220W.
For models -9604 and -9692, on the aux 1 channel, output ripple and
noise is measured 6 inches down the output cables through a 1 foot long
twisted pair terminated with a parallel combination of a 10µF electrolytic
and a 0.1µF ceramic capacitors. For all other channels on all models,
ripple and noise is measured directly at the output terminals.
No shutdown or latch-up occurs; voltage is internally limited to specified
range.
Aux. 2 tracks Aux. 3, Aux. 4 not adjustable.
Aux. 3 tracks Aux. 2.
Output is not adjustable.

The auxiliary channels must share power as indicated by graph 2.
The maximum output power is 220W.
A minimum of 300LFM of forced air cooling is required for proper
operation of the CMP350.
All outputs must be derated linearly from maximum specified loads during
operation above 50
°
C.
Current share is a single wire share circuit that allows the main output on
multiple CMP350 units to be operated in parallel. Auxiliary channels share
on -9604 and -9692 models by connecting the CSAUX channel.
The power fail detect and power OK signals are open-collector outputs
which will sink 40mA or less in the low state and should be pulled up to a
bias voltage with an appropriately sized resistor.

14 Connection from TRIMAUX2 to AUX1SET causes the output for Ch. aux. 1
on models -9604 and -9692 to regulate at its nominal factory set voltage.

16 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
TRIMAUX2 is connected to
AUX1SET by a factory fitted
jumper to ensure CH. 1
regulates at the nominal
set voltage
To trim CH1, remove the
jumper and connect a resistor
between GND3
and TRIMAUX2
