PKM-A series

100-150W Quarter Brick Isolated DC/DC Converters for Industrial & Railway applications

The PKM-A series is an encapsulated 100-150W DC/DC converter in a standard quarter brick format, designed for industrial and railway applications. The series currently consists of two versions - PKM7000A which is an EN50155 compliant DC/DC converter with 16-160V input for Railway applications, and the PKM8000A which has a 9-75V input for Industrial applications.

The PKM7000A series offers a high 89% efficiency at half load at 24Vout. Output voltage configurations of 5V, 12V, 15V, 24V, 48V, and 54V are available. All models offer a wide input voltage of 60-160Vin. The encapsulated design makes it suitable for harsh environments, and input to output isolation is 4000Vdc. It meets IEC/EN/UL 62368-1 safety requirements and is also EN50155 compliant. It also meets the EN45545-2 standard for fire safety.

The PKM8000A series offers an efficiency of up to 91% at 54V out and half load , and output voltages of 12V or 54V are currently available. The input voltage range is 9-75V, and the isolation voltage in this case is 3000Vdc. This series meets IEC/EN/UL 62368-1 for safety.

Standard features include output over voltage & temperature protection, input under-voltage protection, short-circuit protection, monotonic startup, and remote sense & remote control.
