DC power supply for industrial systems
The CHB300W-48S28 accepts a wide 18-75 V input and delivers a regulated 28 V output at up to 10.7 A. Rated for 300 W, it suits telecom, automation and embedded equipment that run from a 48 V bus. The unit is new and tested working before dispatch.
Sustained-load behaviour
Continuous operation at the full 300 W rating is supported within the specified input range. The 19.5 A maximum input current reflects worst-case draw at low line voltage. No derating curve or thermal limits are supplied, so designers should verify cooling for their enclosure.

商品問答
How much heat does the CHB300W-48S28 generate when running at 300 W continuously?
At full 300 W load the unit draws up to 19.5 A from the 18-75 V source, so waste heat equals the difference between input power and the 28 V 10.7 A output; ensure adequate airflow around the supply.
What input connector or wiring must I already have to connect the 18-75 V source to this supply?
The supply accepts a 18-75 V DC source capable of delivering 19.5 A; you need appropriately rated cables and a connector matching the unit's input terminals.
