●
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 affect the AC
supply due to current 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 rotary 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.
●
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 264 V.
Each model is ready to accept worldwide power sources without switching
over the voltage selector.
