Q Series Data Sheet 66 132 Watt DC-DC Converters Features RoHS lead-free-solder and lead-solder-exempted products are available Class I equipment Compliant with NFF-16 and EN 45545 (version V106 or later) Wide input voltage ranges up to 154 VDC 1 or 2 isolated outputs from 3.3 to 24 V Flexible output power Extremely high efficiency of up to 90% Excellent surge and transient protection Outputs open and short-circuit proof Redundant operation, current sharing Extremely low inrush current, hot-swappable Externally adjustable output voltage and inhibit Electric strength test 2.1 kVDC Extremely slim case (4 TE, 20 mm), fully enclosed 111 4.4 Safety-approved to IEC/EN 60950-1 and UL/CSA 3 U nd 60950-1 2 Ed. 164 20 6.5 0.8 1 4 TE 1 on request Description indicate the status of the converter. Test sockets at the front panel allow for a check of the main output voltage. These extremely compact DC-DC converters incorporate all necessary input and output filters, signaling and protection Full system flexibility and n+1 redundant operating mode are features, which are required in the majority of applications. The possible due to virtually unrestricted series or parallel con- converters provide important advantages such as flexible nection capabilities of all outputs. In parallel connection of output power through primary current limitation, high efficiency, several converters, automatic current sharing is provided by a excellent reliability, very low ripple and RFI noise levels, full single-wire interconnection. input to output isolation, negligible inrush current, over- As a modular power supply or as part of a distributed power temperature protection, and input over-/undervoltage lockout. supply system, the extremely low-profile design reduces the The converter inputs are protected against surges and necessary power supply volume without sacrificing high transients occurring on the source lines. reliability. A temperature sensor disables the outputs when the The converters are particularly suitable for rugged environ- case temperature exceeds the limit. The outputs are ment, such as railway applications. They have been designed automatically re-enabled, when the temperature drops. in accordance with the European railway standards EN 50155 The fully enclosed, black-coated aluminum case acts as a heat and EN 50121-3-2. All printed circuit boards are coated with a sink and an RFI shield. The converters are designed for 19 protective lacquer. DIN-rack systems occupying 3 U/4 TE only, but can also be The outputs are continuously open- and short-circuit proof. An chassis-mounted by four screws. Fitting an additional heat isolated output Power Good signal and LEDs at the front panel sink or ordering options with fitted heat sink is possible as well.
