BHK-MG models are designed for
bench or rack mount use with both
front and rear output terminals. Two
operating modes are available:
conventionally filtered (slow mode) for
use as a fixed or slowly varied voltage
source. In this mode, the output
capacitor provides excellent energy
storage to support transient loads. A
fast mode is also available. In fast mode,
the output capacitor is disconnected and
the power supply depends on its fast­responding feedback loop to suppress
ripple and noise. Fast mode is ideal
for operation as a current source or as

a rapidly programmed voltage source
where the energy storage of a conven­tional output capacitor would inhibit
the output voltage’s agility.

Control is either analog or digital.
Analog control is based on the idea of
an operational amplifier in which the
power supply output is programmable
from zero to maximum with a 0-10V
signal. Digital control is IEEE 488.2
using a built-in interface that
supports SCPI. Resolution is 12 bits
and controls both voltage and current.
A front panel keypad provides local

control. Both digital control (local or
remote) and analog control can be
inputted simultaneously.

The display is an alphanumeric
two-line LCD which provides both
setting values and actual voltage and
current readings.

BHK-MG use a solid state FET­based high voltage output stage.

BHK-MG comply with EN61010-1
safety standard for measurement
control and laboratory use equipment
and carry the CE mark.

(1) The full rack BHK-MG have 10:1 current ranging. By command selection from the keypad or GPIB, the full 12-bit control resolution is available across 0-10% of the current rating.
