RODUCT DESCRIPTION
The Dimension CP-Series are cost optimized power
supplies without compromising quality, reliability
and performance. The most outstanding features of
the CP20 series are the high efficiency, electronic
inrush current limitation, active PFC, wide operational
temperature range and the extraordinary small size.
The CP20.241-C1 is equipped with conformal coated
pc-boards preferred for applications in harsh areas.
The CP20.241-S1 is equipped with quick-connect
spring-clamp terminals preferred for applications
which are exposed to mechanical vibration. The
CP20.241-S2 has push-in terminals optimized for easy
cabinet wiring.
The CP20.241-V1 is equipped with a remote ON/OFF
feature.
The devices have a power reserve of 20% included,
which may even be used continuously up to +45°C.
High immunity to transients and power surges as
well as low electromagnetic emission, a DC-OK relay
contact and a large international approval package
make this unit suitable for nearly every situation.

The output is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors, such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance >1F are connected to the output, the unit might charge the capacitor in an intermittent mode.

    CP20.241 CP20.241-S2 CP20.241-C1 CP20.241-V1 CP20.241-S1 25.2. OUTPUT CIRCUIT BREAKERS Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and may also be used on 24V branches. MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.

Check CP20.241-Rx units. 1+1 Redundancy: Devices can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case one device fails.

    CP20.241 CP20.241-S2 CP20.241-C1 CP20.241-V1 CP20.241-S1 25.5. SERIES OPERATION Devices of the same type can be connected in series for higher output voltages. It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc must be installed with a protection against touching.

USE IN A TIGHTLY SEALED ENCLOSURE When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. In such situations, the inside temperature defines the ambient temperature for the power supply. The power supply is placed in the middle of the box, no other heat producing items are inside the box.

    CP20.241 CP20.241-S2 CP20.241-C1 CP20.241-V1 CP20.241-S1 25.9. MOUNTING ORIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature. The listed lifetime and MTBF values from this datasheet apply only for the standard mounting orientation. The following curves give an indication for allowed output currents for altitudes up to 2000m (6560ft).
