CLP0212 Open Frame Power Supply
90 - 264Vac input; 12Vdc output; 200W Output Power
Preliminary Data Sheet
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
power supply operation is disabled. The power supply will
begin to operate at an input voltage above the undervoltage
lockout turn-on threshold. Note that the undervoltage lockout
limits are load dependent and the power supply turns ON and
can operate at much lower input voltage levels when at light
or no load.
DC OK
The CLP0212 provides a DC OK signal that indicates when
the output has come up and is in regulation. This is an open-
collector type signal that goes high when the output is
available and within regulation.
Power Good LED
A green LED (located next to HDR3) illuminates when the main
output voltage is above 10V.
Paralleling/Load Share
This power supply can be paralleled to provide larger load
currents than can be delivered from a single power supply. Up
to four power supplies may be paralleled. Paralleling is
accomplished by connecting the Current Share signals of
multiple power supplies together. At load current levels above
20%, the output currents of multiple power supplies will be
within ±5% of the full load value.
If remote sense is used when paralleling is employed, the
remote sense connection points should be common to both
power supplies.
For applications where redundancy among paralleled power
supplies is desired, ORing diodes or other active ORing circuitry
needs to be connected in series with each output.

Operation In a Sealed Enclosure
The CLP0212 power supply can also be operated in a sealed
enclosure provided proper means for removing heat from the
power supply are used. Figure 12 shows an arrangement
where a thermally conductive pad is used to transfer heat
from the bottom of the power supply into the enclosure. Under
such conditions, the power supply is capable of reduced power
operation as shown in Table 1.

Thermal Considerations
The power supply can be operated in a variety of thermal
environments; however sufficient cooling should be provided
to ensure reliable operation.
Considerations include ambient temperature, airflow, power
supply dissipation and the need for increased reliability. A
reduction in the operating temperature of the power supply
will result in increased reliability. The thermal data presented
here is based on measurements taken in a wind tunnel.
Heat Transfer via Convection
Increased airflow through the power supply enhances the heat
transfer via convection. Figure 11 shows the preferred airflow
direction. Contact your GE Energy technical representative for
derating information in other airflow directions.
Note: Under Natural Convection cooling conditions, the
maximum load is restricted to 100W as OTP will be triggered
at higher loads.
