Single Output Programmable DC Power Supplies

Models 9150, 9151, 9152 & 9153

B&K Precision®models 9150, 9151, 9152 and
9153 are high performance linear-regulated
programmable DC power supplies that provide
excellent performance and features not found in
other supplies in this price category. The 9150
series are designed for applications in design
verification, production or university labs that
require high yet clean and reliable power,
combined with excellent resolution, accuracy and
fast transient response time.

■ Excellent display resolution

■ Low ripple and low noise due to linear

regulation

■ Outstanding temperature stability

■ Fast transient response time (<120 µs)

■ SCPI compatible command set, programmable

via USB and RS232

■ Closed case calibration

■ List mode operation for increased throughput.

Download and execute command sequences
from non-volatile memory

■ For bench use or rack mountable

■ Very quiet due to intelligent fan speed control,

making the supply suitable for lab bench use

■ Over voltage protection

Application Software

The included Application Software supports front
panel emulation and allows users to generate

simple test sequences without the need to write
source code.

Front Panel Operation

The numeric keys and rotary knob provide a
convenient interface for setting output levels
quickly and precisely. Voltage and Current can be
set to a maximum resolution of 0.5 mV (0.1 mV
for 9150) and 0.1 mA (1 mA for 9150)
respectively. Up to 50 parameters can be stored
and recalled from internal memory.

Additionally, the power supply comes with a
built-in 5 1/2 digit Voltmeter and high resolution
Milliohm meter supporting 4 wire measurements

Remote Interface

The power supplies can be remotely controlled
from any PC with USB or RS232 interface,
allowing the user to program and monitor all
parameters through easy to use SCPI commands.
The power supplies come with a RS232 to TTL
and a USB to TTL serial converter cable. The
average command processing time is 35 ms.
