The PDS Series are CE-certified Regulated DC Power Supply units which comply with Power Supply Harmonics Current Regulations IEC1000-3-2‚ and a power factor of 95% (typical) is cleared. These models feature high reliability and various types of protection‚ and can be used as a power supply for reliability tests‚ endurance tests‚ aging and other electronics parts tests.

By employing a unique switching and dropper circuit systems‚ the output noise is maintained at a minimized level.The input AC voltage is possible from 90 to 246 volts without any modification. Furthermore‚ these models are designed in a smaller size and a lighter weight compared to conventional models.

This is a used unit and has been tested and calibrated to be in perfect working condition, guaranteed against DOA. Item Sold AS IS. Sorry no instruction manual & accessories included, the machine is clean with minor scuffs and scratches. 

Features:

• 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.
