HPF3K0 programmable, remotely controllable, 3-kW power supply provides distributed control and monitoring. Its digital signal processing “engine” incorporates digital control and monitoring functions that allow dynamic variation of power configurations and performance, including constant current operation, variable overload characteristics and alarm functions. Conseequently, HPF3K0 can adjust current and/or voltage down to 0% of nominal rating. Its graphical user interface (GUI) allows configurations to be developed and evaluated.
HPF3K0 uses multiple serial protocols, including I2C, PMBus, RS485 and CANopen. These allow seamless integration with remote control schemes, while a boot loader function allows remote firmware updates for maintenance or enhancement. It also features an auxiliary signal connector with positive locking and double fixing points on output terminals. HPF3K0 is housed in an enclosed, steel chassis measuring just 280 x 178 x 64 mm (11.0 x 7.00 x 2.50 in.). Up to five units can operate in parallel via one wire bus, providing up to 15 kW of flexible power.
Four variants are available with nominal, single outputs of 24, 36, 48 and 60 VDC. Efficiency is as high as 93%, and cooling is via an integrated fan with intelligent control that ensures audible noise is kept at the lowest level possible. Also, output voltage rises and falls are strictly controlled to avoid standing voltage on the output capacitors.
HPF3K0 is approved to meet the requirements of IEC 60601-1 Ed. 3 with 2X means of patient protection (MOPP). It also complies with EN55011/EN55032 for EMC Class B (conducted) and Class A (radiated), as well as EN61000-4-x for immunity. ITE approvals include IEC 62368-1, Ed.2.
