Description
In a small 2 x 4 inch footprint, the 12Vdc single-output CLP0212 open frame power supply delivers 80 PLUS Gold energy
efficiency. W i t h i t s s m a l l s i z e , t he CLP series is specifically designed to handle power challenges associated with tight
space and low airflow. Offering a leading 18W/in3 power density in a 1U high, fan- less form factor, the CLP series addresses a
broad range of applications in new products from communications, computing and data storage original equipment
manufacturers (OEMs). It delivers greater than 90 percent typical power efficiency and full load output at +50˚C (122˚F) with
higher temperature operation possible at derated output. The CLP series utilizes a unique design approach at this power level,
leveraging zero voltage switching techniques in conjunction with quasi-resonant power factor correction (PFC) circuits.
Protection features include overcurrent (OCP), overvoltage (OVP), and overtemperature (OTP).

Safety Considerations
Output Voltage Adjustment
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).
Potentiometer
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.
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.
CLP POWER SUPPLY
STANDBY OUTPUT
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 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.

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.

90 - 264Vac input; 12Vdc output; 200W Output Power
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 opencollector type signal that goes high when the output is
available and within regulation.
Fig. 11. Preferred airflow direction for cooling.
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.
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.
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.
Enclosure Wall
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

direction. Contact your GE Energy technical representative for
