Technique

The programmable laboratory power supply HM7044 comes equipped with four independent and isolated power sources. Each output voltage is continuously variable between 0-32V up to 3 A. All outputs can be connected in series (up to 128V, 3A max.) or in parallel for a higher current output (up to 12A). Voltage tracking can be used with up to four outputs. User-defined voltage and current settings and an extensive set of protection features have been included, making the HM7044 a versatile and reliable instrument especially in R&D applications.

Voltage source or current source

The power supply can act either as voltage source or as current source, depending on the load conditions and output values. Voltage and current settings are made by the rotary dial, key pad or via the RS-232 interface.

Programmable current fuses

All outputs are equipped with an electronic current fuse. Over current limit values can be set by the user. When a limit value is reached, power is removed from the output within less then one millisecond. An overload in one output will shut down all other outputs simultaneously or up to four outputs pre-selected by the user. This is an important feature to protect the device under test from overload, especially for applications requiring positive and negative balanced voltages such as operational amplifiers.

Pre-set configurations

For repeatable calibration and adjustment procedures in production environments user-defined voltage, current and fuse settings are recalled by only one front panel setting.

Sense mode

Voltage and current are constantly monitored by a sense controller. With the sense lines, voltage is directly measured at the load and used to compensate any voltage drop across the supply lines. If any of the sense or supply lines is interrupted, the result will be displayed on the corresponding display. On production lines, cables of several meters between the power supply and the device-under-test (DUT) are continuously monitored for safe operation.

Operating comfort

An additional operating benefit is that the output power of all outputs or only user-defined outputs can be turned on and off with only one front panel key. So the entire power supply need not be switched off (Standby mode).

Reliability

Reliability of power supplies is of extreme importance. The Hameg programmable power supplies are designed and manufactured for years of trouble-free life.
