Calex BPS4000 Triple Output Bench Top Power Supply
4 to 6 VDC,
12 to 12 VDC,
–12 to –15 VDC
The BPS4000 provides three fully stabilised and smoothed variable DC power sources.
The voltages can be adjusted by rotating graduated controls on the front panel.All three outputs are
short circuit and reverse connection protected.
Additional protection is provided by current limiting and an internal thermal shut-down mechanism.
A 20mm x 5mm mains fuse accessible from the rear panel provides further protection
SPECIFICATION
Mains Input 240VAC (±7.5%) 50Hz via 1 metre 3-core cable,
on/off switch and 20mm x 5mm mains fuse rated 0.5A
Power-on Indication
LED on front panel
DC Output 1
4 to 6V, adjustable by front panel control. Maximum
current 0.5A. On this output the indicated area on the
front panel is for T.T.L. applications and provides a
reminder of the voltage range (4.75 to 5.25)
DC Outputs 2 & 3
+12 to 15V and –12 to 15V. The two outputs share a
common 0V, are adjusted simultaneously by a single
front panel control and are isolated from output. 1.
Maximum current 0.5A.
Protection
All 3 outputs have an internal current limit of
approximately 1A for overload protection.
Load Regulation
Typically 0.5% (all outputs)
Ripple and Noise
Typically 5mV rms (all outputs)
Termination
For use with 4mm wander plugs or as a
binding post for wire connection.
Dimensions (h x w x d)
76 x 160 x 138mm
Weight
1.5kg
OPERATING INSTRUCTIONSThe AC input to the unit is via a three core mains lead to
which a suitable plug must be attached. Fit a 3A mains
fuse
Note these units must be earthed via the mains input
yellow/green lead. Do not obstruct the ventilation holes
in the unit case.
DC OUTPUTSThe variable DC output voltages are available by connecting
suitable leads to the red and black screw terminals situated
on the front panel. The output voltages are adjustable
over the range indicated by turning the control knobs
