Description
The HBC Series of high density bus converters convert a worldwide telecom bus voltage of 36 to 75VDC to a 12V bus at 25A. The output is ideal for powering non-isolated, point-of-load converters such as synchronous buck converters used commonly in intermediate bus architectures. The unit's open-frame, two-board construction provides ideal thermal transfer for maximum reliability. Power devices are mounted on an Insulated Metal Substrate (IMS) base plate with very low thermal impedance. The control PCB is physically isolated from the hotter IMS board, providing lower overall component temperatures for high reliability. The standard feature set includes remote on/off, remote output voltage sensing, positive output trim, input undervoltage lockout, and overtemperature shutdown with hysteresis.

- If the voltage source feeding the module is SELV or TNV-2, the output of the converter may be grounded or ungrounded.
- If the voltage source feeding the module is ELV, the output of the converter may be considered SELV only if the output is grounded per the requirements of the standard.
- If the voltage source feeding the module is a Hazardous Voltage Secondary Circuit, the voltage source feeding the module must be provided with at least basic insulation between the source to the converter and any hazardous voltages. The entire system, including the HBC converter, must pass a dielectric withstand test for reinforced insulation. Design of this type of systems requires expert engineering and under- standing of the overall safety requirements and should be performed by qualified personnel.
