Compact, Lightweight Design
When compared with the conventional PD-A Series, the weight is
reduced to 1/2 to 1/3. It can more easily be carried from door to
door than before.
Various Protection Functions
For protection, various protection functions are provided including
OVP (over-voltage protection), OHP (over-heating protection) and
OCP (over-current protection). When a protection circuit is
engaged, the power switch is automatically turned off.
Board-Type Options for External Control
External control is possible using optional board interface. Since a
board can be mounted inside the unit, no extra mounting space is
required. For external control, three types of options are available
-- analog (voltage/resistor), GP-IB and RS-232C.
Worldwide AC Voltage Input Design
A wide range of AC power voltages can be input between 90 V and
246 V. Each model is ready to accept worldwide power sources
without switching over the voltage selector.
77
Complies with Power Supply Harmonics Current Regulation,
and a Power Factor of 95% (typical)
The PDS Series comply with Power Supply Harmonics Current
Regulations (IEC1000-3-2) as well as "Home Appliance and
General-Purpose Products Harmonics Suppression Control
Guidelines", and never af fect the AC supply due to cur rent
harmonics. Furthermore with a built-in active smoothing filter, a
resulting power factor of 95% (typical) is cleared.
Satisfying CE Mark Certification Requirements
These models satisfy Low-Voltage Standards (IEC1010) and EMC
Standards Requirements.
Series/Parallel Operation
When these models are connected in series, the resulting output
voltage is increased. And when they are connected in parallel, the
resulting output current is increased. For more convenience,
when a master-slave system is used, either a series drive or a
parallel drive operation can be performed by a single unit in order
to control the output of all of the other units.
(A master-slave system is possible with up to 3 units in parallel
mode, and up to 2 units in series mode.)
Voltage/Current Simultaneous Digital Display
The bright and easy-to-see displays with 7-segment red LEDs are
designed to display the voltage and current values digitally at the
same time.
Voltage/Current Preset (3 points)
The frequently used output values for voltage and current can be
stored in the memory for up to 3 points for each value. The preset
values can be recalled with a touch of a button, making possible
the switching of the output value more quickly.
Single-Dial Control Design
Designed with easy operation in mind, the operation conditions
can be set at a press of the push button switch, while all the setup
values can be changed using the rotar y encoder control.
Especially for output voltage and current, high accuracy control is
possible in 10 mV and 10 mA steps respectively. Furthermore, the
variable speed of the control knob can be switched between
SLOW and FAST.
Key Lock Function
A key lock function is provided to fix the setup values for
inhibiting the operation on the front control panel. This is
convenient when long-term energization is required. Also, it is not
necessary to have to worry about mis-operation by others if you
leave it on your desk while the experiment is continuing.
