500W High Voltage DC Power Supply
The CDC150HV-24 is a high-performance DC/DC converter featuring a single galvanically isolated 24 Vdc output derived from a high-voltage input of up to 1000 Vdc.
The CDC150HV-24 is suitable for use as an auxiliary power supply in applications that require a 24 Vdc supply to be generated from the high-voltage DC-bus rail or DC micro grid, that is typically found in electric vehicle chargers, energy storage, renewable energy and industrial power systems.
The CDC150HV-24 has a very high efficiency that allows for a compact and fan-less design, capable of operating at elevated ambient temperatures while still maintaining very high reliability and long-life expectancy.
Up to 10 units can be paralleled via a simple 1-wire load share bus for a maximum system power level of 5 kW. The load is shared equally among all active units connected to the load sharing bus. The master unit controlling the load sharing is automatically selected among the active units feeding the load and the master role is automatically passed on to a different unit, should the master encounter a fault. This feature is advantageous over other load sharing methods, especially in high availability applications.
The power density of the CDC150HV-24 is very good with an output power level of 500 W in a compact enclosure size of just 258x124x61 mm.
