Safety Considerations
The CLP0212 power supply is intended for inclusion in other
equipment and the installer must ensure that it is in
compliance with all the requirements of the end application.
This product is only for inclusion by professional installers
within other equipment and must not be operated as a
stand-alone product. The power supply meets Class 1,
IEC60950, EN60950, with the following deviations: Nemko. UL
60950 (Recognized Component) C-UL (Canadian Approval by
UL).
Feature Descriptions
Standby Power Supply
A standby output in the CLP0212 power supply of either 3.3
or 5V, comes on when AC input in the operating range is
applied. In the Z02A and Z03A versions of the power supply,
the standby output is not accessible.
Remote On/Off
All versions of the CLP0212 power supply except the Z02A
and Z03A versions feature a TTL-compatible On/Off control
input. The power supply turns ON when the On/Off input
goes low, and turns OFF when the input goes high. Note
that if the On/Off pin is left unconnected, the power supply
main output remains off.
Figure 9 shows the circuit configuration for using the On/Off
pin. Either a suitable semiconductor device such as a BJT or
FET or a mechanical switch can be used to turn the power
supply On and Off. The switch must be capable of handling
the On/Off pin current which may be up to 6mA when
closed. The switch On voltage drop must also be sufficiently
small so that the photo diode inside the power supply is
turned ON when the external switch is ON.
Note that the standby output voltage could be either 3.3V or
5V depending on the CLP0212 power supply variant
selected. If no On/Off control is desired, the On/Off pin can
be externally connected to the COM pin and the power
supply will automatically turn ON when AC input is within
range.

Output Voltage Adjustment
Fig. 10. Diagram showing location of the potentiometer
used to adjust the power supply output voltage.
The output voltage can be adjusted between 11.4V and 12.6V
using a potentiometer on the power supply. See Fig. 10 for a
diagram showing location of the potentiometer.
Remote Sense
The power supply has both positive and negative remote
sense connections that can be connected to the positive
and negative rails of the main output near the load. Care
should be taken in routing the sense lines to ensure that
noise is not picked up or that additional filtering elements
that affect the stability of the power supply are not used.
The power supply will operate without the remote sense
connections being made, however if remote sense near the
load is not used it is recommended that the remote sense
lines be connected directly to the main output terminals.
Overcurrent Protection
To provide protection in a fault condition (output overload), the
power supply is equipped with internal current-limiting
circuitry and can endure current limiting continuously. At the
point of current-limit inception, the unit enters hiccup mode.
The power supply operates normally once the output current is
brought back into its specified range.
Overvoltage Protection
Overvoltage protection is a feature of the CLP0212 power
supply that protects both the load and the power supply from
an output overvoltage condition. When an overvoltage occurs,
the power supply shuts down and goes into hiccup mode until
the overvoltage condition is removed. It is not necessary to
recycle the input to restart the power supply when this
protection is activated.
Overtemperature Protection
The CLP0212 also features overtemperature protection in
order to provide additional protection in a fault condition. The
power supply is equipped with a thermal shutdown circuit
which detects excessive internal temperatures and shuts the
unit down. Once the power supply goes into overtemperature
shutdown, it will cool before attempting to restart. The
overtemperature protection circuit will typically activate when
the unit is operated at 200W output with an ambient
temperature of 60ºC and 1m/s (200LFM) airflow.
