The PST23 , very compact DC-DC converter in chassis mount format, incorporate input filtering, input and output protections, very robust mechanical mounting and connection,optional conformal coating, required in most of the severe environment for industrial, railways type of applications. The converter provides high reliability thanks to the integration of Vicor Corp. modules, high efficiency, input-to-output isolation, soft start, overtemperature protection, input over/undervoltage lockout. The converters wide range of inputs are protected against surges and transients and EMI filtered. The outputs are countinuously short-circuit proof .The 100°C baseplate operation allows operation in high temperature environment. The output can be configured in many different output voltages from 3V3 to 48Vdc , others possibilties are even possible as semi-standard versions.

Input Fuse
An internal fuse protects against damages in case of a failure. The fuse is not user-accessible. Reverse polarity at the input will cause the fuse to blow .

Input Transient Protection / Electromagnetic Compatibility (EMC)
A VDR (Voltage Dependent Resistor) and a common mode input filter form an effective protection against input transients in severe environment like railways with EN50155.
Input Reverse polarity Protection
A diode placed internally across the input will cause the fuse to blow in case of a reverse polarity of input voltage .
Primary Inhibit (Remote On/Off)
The inhibit input disables (logic low, pull down or short circuit between Inh+ and Inh-) or enables (logic high TTL, pull up or open-circuit between Inh+ and -In) the converter. This signal is referenced to the input voltage and will disable/enable all outputs at the same time. In systems consisting of several converters, this feature may be used to sequence the activation of the different converters.
Output Voltage Adjustment
The converter offer adjustment for output voltage though a potentiometer.

Parallel and Series Connection
PST23 Rev. 04 Page 4 of 9 www.powersystemtechnology.com
A converter output can be connected in series with an output from a separate converter, an external diode across each output is required. The maximum output current of a serial-connected outputs is limited by the output with the lowest current limit.Output voltages above 48V (SELV - Safety Extra Low Voltage) require additional safety measures in order to comply with international safety requirements.Parrallel operation is possible with the addition of external diodes in series with each output.
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 of converter to support power requirement. If one converter fail, the remaining ones still delivers the power to the loads.The external diodes are required with the PST23 to ensure proper N+1 operation .
Hold-up time
The converter provides low hold-up time. If a hold-up time is required (some railways applications for example) , use external input capacitors of adequat size. Formula for additional external input capacitor : C =2*Pout*th*100/(V²-Vi²)/nwhereas :C = external input capacitance [mF]Pout = output power [W]n = efficiency [%]th = hold-up time [ms]Vi = minimum input voltageV = Input voltage level before interruption
Output Current Limitation
The converter output is continously protected against short-circuit by a constant current limitation (no foldback). The short circuit protection is unlimited , the operating area between nominal power and active protection area working in a constant current mode may lead to power above nominal , then over stress of the internal components.
Thermal Considerations
The converter is designed to be mounted on a dissipative area, in conduction cooling mode.The max. operating temperature is the temperature of the base-plate which should not exeed 100°C.Addition of grease or thermal pad between the converter baseplate and the chassis is mandatory .
Thermal protection
A temperature protection is integrated internally, disabling output when heatsink temperature exceed 105°C . The converter automatically restart, when the temperature drops below this limit.

Installations Instructions
PST23 Rev. 04 Page 8 of 9 www.powersystemtechnology.com
These converters are components, intended exclusively for integration into other equipment by an industrial assembly process or by a professionnaly 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 female connector FAST ON.The +Vin 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 fuses in the wiring circuit to one or both input pins may be necessary to ensure compliance with local requirements.Do not open the converters, or the warranty will be invalidated. Make sure that there is sufficient heat dissipation available for conduction cooling. This should be verified by measuring the case of temperature at the specified measuring point, when the converter is operated in the end-use application.
Cleaning Agents and Process
The converters are not hermetically sealed. In order to avoid possible damage, any penetration of liquids shall be avoided.
Railway Application
The converters have been designed observing the railway standards EN 50155 and EN 50121. All boards can be protected by a conformal coating as an option ( -V).
Isolation
The electric strength test is performed in the factory in accordance with IEC/EN 60950.
Standards and Approvals
The converters are built to meet the safety standards IEC 60950-1, EN 60950-1, UL 60950-1 and CSA 60950-1.
