No derating. Safety IEC/EN 62368-1, RoHS lead-free-solder compliant The PST21A, very compact and low profile AC-DC power supply up to 1200W in chassis format, incorporates input filtering, input and output protections, very robust mechanical mounting and connection, conformal coating and MIL-STD options required in most of the severe environment for industrial, defense applications. The psu provides high reliability thanks to the integration of Vicor Corp. modules, high efficiency, input-to-output isolation, soft start and active very low inrush circuit, overtemperature protection, input over/undervoltage lockout. The psu is configurable with 1 to 6 outputs in many output voltages from 2V to 54Vdc, other outputs are even possible as semi-standard versions. They are countinuously short-circuit proof. The 100°C baseplate allows operation in high temperature environment. Bloc diagram POSITION A ACTIVE INRUSH CURRENT LIMITING + PFC

Options Description MIL-STD ruggedized (-M) Meet MIL-STD 461E CE102, MIL-STD 1399-300A, MIL-STD810E shock & vibrations. No Laboratory certification. The thermal grade of the Vicor the DC/DC converters used and other components are changed to comply with low ambiant temperature. Conformal coating (-V) During manufacturing process , when V option is specified, components and pcb are covered with an acrylic coating to address high level of ambiant humidity application. Output Power -H: a 15 mm heatsink is mounted on the baseplate with longitudinal fins. -H1: a 15 mm heatsink is mounted on the baseplate...

Output Electrical Output Data General conditions : 25°C ambiant. For each output voltage max power configuration. See "options and configurations" section for all the power possibilities.

Input Power Break - PST21A-5300-48150-550-3V375 Parallel operation & current share Parrallel operation is possible in the same unit or between different units for Miniboards, Maxiboards and Dual Maxiboards with active current sharing through the PR signal. The outputs put in parallel MUST be exactly the same, all OUT+ connected together and all OUT- connected together when PR are linked (risk of damage otherwise) . Redundant Systems Operation When systems require a very high level of reliability and should work normally in the event of a failure, N+1 redundancy is implemented where N is the number...

This feature enables compensation of voltage drop across the connector contacts and the load lines. Remote Sense, max 0,5V per line compensation (If local sense, connect locally S+ to OUT+ and S- to OUT- of the corresponding output). Senses are not included on Microboard. Output type Total drop Positive line drop PowerGood & LED Collector isolated optocoupled signal referred to RTN, closed when all outputs voltages are OK. Led is also available for each output. Auxiliary bias voltage (+5VAUX) Auxiliary supply limited to 200mA. Referred to RTN Paralleling signal (PR) Parallel only identical outputs...

CM Safety & Installation These converters are components, intended exclusively for integration into other equipment by an industrial assembly process or by a professionally competent person. Installation must strictly follow the safety regulations in respect of the enclosure, mounting, creepage and clearance distances, markings of the end-use application. Connection to the system shall be made via the male connector Wurth. The AC/L is internally fused. This fuse is designed to protect the converter against overcurrent caused by a failure, but may not be able to satisfy all requirements. External...
