PAH
compensation range should be kept so that the output volt-
age is within the output voltage range and the maximum
power is not exceeded. For long connections and noise
sensitive environments, shielded wires are recommended
to minimize noise pickup on the output leads.
Remote Sensing in Use
Remote Sensing not in Use
 ON /OFF Control (CNT)
Without turning the input supply on and off, the output
can be enabled and disabled using this function. This
control circuit is on the input side of the power module;
CNT terminal pin. There are two options available in this
function, which are Negative Logic and Positive Logic. In
the standard model where Negative Logic is used, the
power module will turn on when CNT terminal pin is short-
ed to –Vin or a low logic voltage is provided. The power
module will turn off when CNT pin is open or Logic high
is provided. In the /P optional model where Positive logic
is used, the control method is vice versa to the Negative
Logic.
Below tables summarize the CNT levels and output states
with different logic types.
a）Negative Logic: (Standard model)
b）Positive Logic: (/P option)
The maximum CNT pin voltage when it is opened is 7V.
The maximum low logic sourcing current is 0.6mA. When
using this function, attach a 0.1µF capacitor between the
CNT and -Vin terminals.
Remote ON/OFF control can also be exercised by opening
or closing the contacts of a switch or relay, or by operating
a transistor as a switch in series with the CNT terminal.
Standard remote ON/OFF control circuit is provided in

（1）Series Operation for High Output Voltage Applications
the primary circuit. For secondary control, isolation can be
achieved through use of an opto-coupler or relay.
CNT Connection Method
 Series Operation
All PAH-S48 SERIES modules allow series operation with
any combination of output voltages. Please contact us for
maximum number of connections possible.
2）+/- Output Series Operation
When using PAH-S48 SERIES modules in a high out-
put voltage configuration external bypassing diodes
need to be connected to either module.
a. Peak Reverse Voltage
b. Average Output Current
c. Forward Voltage
When the load on the positive side is isolated from
the load on the negative side, the following connec-
tion hookup is recommended.
Bypass diodes are not needed when operate in this
mode.
VRRM>2x the power module output voltage
Io>Twice the power module output current
VF = Minimum (Schottky Barrier Type, etc)
