Modular DC/DC converter

Modular DC/DC converters for space application suited for individual voltage conversion in any space electronic equipment.

Standardised DC/DC modules of single, dual and triple output can be arranged in any configuration for multiple output converter systems.

Optional functions like inrush current limiter, on/off switching, protection features and synchronisation interfaces can be realised.

Features / technical details

Provide low voltage, isolated DC power to electronic equipment
DC input voltage range: 28 V to 120 V regulated or unregulated
DC output voltage range: 5 V to >100 V
Power per module: 0 to <100 W
Efficiency: 75 – 90 %
Protection: output over-voltage and over-current; input over-current and under-voltage
Optional features: input latching current limiter, command and housekeeping, synchronization, sequencing of outputs, voltage and current housekeeping etc
Linear or switch-mode output voltage post-regulators

Parts level acc. QML-Q, QML-V and equivalents

The converters are available in rad-hard and SEE resistant version.
