    CP20.242 23.3. YR40.241 - REDUNDANCY MODULE The YR40.241 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems. The device is equipped with two 20A nominal input channels, which are individually decoupled by utilizing MOSFET technology. The output can be loaded with a nominal 40A continuous current.

  • Page 25: Application Notes

    CP20.242 24. Application Notes 24.1. PEAK CURRENT CAPABILITY The device can deliver peak currents (up to several milliseconds) which are higher than the specified short term currents. This helps to start current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil.

  • Page 26: Output Circuit Breakers

    CP20.242 24.2. 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.

  • Page 27: Parallel Use To Increase Output Power

    CP20.242 24.3. PARALLEL USE TO INCREASE OUTPUT POWER Power supplies can be paralleled to increase the output power. The output voltage of all devices 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.

  • Page 28: Parallel Use For Redundancy

    CP20.242 24.4. 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: Power supplies 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.

  • Page 29: Series Operation

    CP20.242 24.5. SERIES OPERATION Power supplies 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.

  • Page 30: Use In A Tightly Sealed Enclosure

    CP20.242 24.8. 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.

  • Page 31: Mounting Orientations

    CP20.242 24.9. 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.
