PRODUCT 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 and the CP20.242 features an enhanced DC

input voltage range.

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 makes this

unit suitable for nearly every situation.

After this, the output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared, the device will operate normally. See Fig. 6-3. Fig.

UF20.241 BUFFER MODULE The UF20.241 buffer module is a supplementary device for DC 24V power supplies. It delivers power to bridge typical mains failures or extends the hold-up time after the AC power is turned off. When the power supply provides a sufficient voltage, the buffer module stores energy in the integrated electrolytic capacitors.

YR40.245 - REDUNDANCY MODULES The YR40.245 is a 40A single channel redundancy module, which is equipped with a plug connector on the output. The plug connector allows replacing the power supply or the redundancy module while the system is running. The plug connector prevents the output wires from touching and creating a short the load circuit.

CHARGING OF BATTERIES The power supply can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VRLA batteries are needed in series connection. Instructions for charging batteries: a) Use only matched batteries when putting 12V types in series. b) Ensure that the ambient temperature of the power supply stays below 40°C.

PARALLEL USE TO INCREASE OUTPUT POWER Devices can be paralleled to increase the output power. The output voltage of all power supplies shall be adjusted to the same value (±100mV) in “Single Use” mode with the same load conditions on all units, or the units can be left with the factory settings. After the adjustments, set the unit to “Parallel Use” mode, in order to achieve load sharing.

PARALLEL USE FOR REDUNDANCY Please note that there are variants with built-in redundancy are available in the CP20 series. 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.
