YR40.242 12-28V, 40A, DUAL REDUNDANCY MODULE MOSFET REDUNDANCY MODULE For N+1 and 1+1 Redundant Systems Dual Input with Single Output Suitable for all DIMENSION Power Supplies Except QT20 and QTD20 Series Only 72mV Voltage Drop at 20A Output Current Only 1.7W Loss at 20A and 5.9W at 40A Output Current 160% (65A) Peak Load Capability Reverse Input Polarity Protection Full Power Between -40°C and +60°C Width only 36mm Rugged Metal Housing Easy Wiring: Distribution Terminal for Negative Pole Included 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA The YR40.242 is a redundancy module, which can be used to build 1+1 and N+1 redundant systems. It is equipped with two input channels, which can be connected to power supplies with up to 20A output current and one output, which can carry nominal currents up to 40A. In addition to the YR40.242, the YR40.241 is also available. This unit has an additional circuit included, which generates a supply voltage for the internal mosfets even when the output of the unit is in a short circuit condition. This makes the unit suitable for any power supplies. Input voltage DC 12-28V Input voltage range 8.4-36.4Vdc Input current 2x 0-20A 2x 20-32.5A Output current 0-40A 40-65A max. 26A The novelty of this redundancy module is the utilization of mosfets instead of diodes for the decoupling of the two input channels. This reduces the heat generation and the voltage drop between input and output. The redundancy module does not require an additional auxiliary voltage. Due to the low power losses, the unit is very slender and only requires 36mm width on the DIN-rail. Large connection terminals allow for a safe and fast installation. The large international approval package makes this unit suitable for nearly every application.

YR40.242 12-28V, 40A, DUAL REDUNDANCY MODULE 5. LIFETIME EXPECTANCY AND MTBF The redundancy module has two input channels which are completely independent from each other. Each control circuit, auxiliary voltage source, or other circuitry in the module are designed separately for each input. The dual input redundancy module can be considered as two single redundancy modules combined together in one housing. The only common point is the circuit trace that ties the two separate circuits together at the output. The MTBF figures below are for the entire dual input module. If the MTBF number of...
