HM7044 4x30V-3A Programmable Power Supply
The HM7044 offers DC voltages from 0 to 32 Volts at each of its 4 outputs and a maximum current of 3Amps at each output. All outputs are independent, electrically isolated. The outputs can be combined in either a series or parallel array to either increase the voltage (max. 128V) or the current (max. 12A) capabilities.
Voltage tracking mode is enabled in any output combination. E.g. output I and II as one tracking pair and output III and IV as the second tracking pair.
In addition to the HM7044 current and voltage control functions, each output has an over current protection circuit. The latter switches the output off if the maximum permissible current has increased, instead of limiting the current. The over current switch off function can also be set in such away that it effects several selected outputs at the same time, if over current occurs on one of these outputs.
Voltage drop on the load cables is compensated automatically over a wide range in combination with SENSE at each output.
For power efficiency the HM7044 is equipped with a controlled switched mode power supply for each output stage. These are followed by controlled linear output stages with the advantage of low ripple and noise at the output.
The HM7044 can be operated manually or via the built in RS232 interface.
