Wide Range DC Power Supply (CV/CC)PWR Series

Three types of wide-range power supplies covering 80 V to 650 V

The PWR Series offers constant voltage (CV)/constant current (CC) automatic crossover DC power supplies that enable you to combine a wide range of voltages and currents within the output power rating.For example, the model that has an output power rating of 1600 W (PWR1600L) provides a seamless operation range from 80 V – 20 A to 16 V – 100 A. With a single PWR Series power supply alone, you can cover an extensive output range equivalent to what is provided by three to six conventional single range DC power supplies. L type can output up to 160 % of the output current rating (in the continuous and intermittent extended operation areas). PWR1600L supports a maximum output of 10 V – 160 A.

Features

Extended operation areas:The L type offers extended operation areas equivalent to up to 160% of the output current rating. Some of the specifications may not be satisfied in the extended operation areas.

Continuous extended operation area
(up to 120 % of the output current rating): Continuous current output is enabled.However, derating occurs at an ambient temperature 30 ̊C or higher.
Intermittent extended operation area
(120 % to 160 % of the output current rating): Continuous current output is enabled for 10 minutes or less. However, a nonoperating period more than twice the output period must be taken.

Very Convenient and Economical Power Supplies That Serve Multiple Purposes.

The PWR series contributes to applications in which the environment greatly changes, such as tests with varying voltages and currents and research and development experiments with the voltage and current ranges varying widely depending on the item under development.

Car electronics components
EPS motor, Radiator, Fan motor, DD converter, Vehicular harness, ECU, Door lock, Power window, HID lamp, etc.
Electronic components
TFT back light, photovoltaic inverter, DD converter, etc.
Batteries
Lead battery, sealed battery, etc.
Communication equipment
Switches, communication servers, etc.
Tests
Suitable for applications for which a test voltage or current is not determined

Front Output Terminals Included as Standard.

The power supplies have front output terminals (up to 30 A) for desktop use.

Parallel Operation Possible

Parallel operation enables multiple power supplies of the same model to operate in parallel, offering a large capacity of up to 8 kW (when five 1600-watt models are connected in parallel).

Digital Communication Function (TP-BUS) Included as Standard.

In addition to an analog external control, a digital communication function (TP-BUS) is included as standard. When used with a power supply controller (PIA4830), which is an option to be purchased separately, the function enables up to 32 PWR series power supplies to be controlled using the GPIB or RS232C interface. In addition, the sequence generation software (Wavy for PWR+PIA4830), allows users to exert output control over a single PWR series power supply with sequence patterns of their choice and to read result data. (If controlling more than one power supply with Wavy, contact us for consultation.)

Seamless five times variable voltage/current range(Note: For H type, 3.25-time variable voltage/current range)

A single PWR Series power supply supports an extensive operation range,covering an output range equivalent to what is provided by several conventional single range DC power supplies. Also, the maximum output powers of the power supplies of this series are 800 W and 1600 W – slightly higher than those of their predecessors. You can conduct tests without worrying about power limits.

Best for testing a wide variety of high-voltage devices including margin tests

The maximum output voltage of L type is 80 V. For example, 150 % of 42 V (63 V) can be supplied for testing vehicular electrical components, or 150 % of 48 V (72 V) can be supplied for testing communication equipment. In addition, the M type (320 V) is suitable for checking designs of energy-saving circuits for flat display panels and the development of new materials, while the H type (650 V) can be used to test various components and devices that use high voltages such as automotive devices, photovoltaic inverters, and many more.

Two extended operation areas where up to 160 % of the output current rating can be output (L type only)

In the extended operation areas, the power supply can output up to 160 % of the output current rating. This feature is convenient when testing an automobile motor or other load device that requires high current at startup time. Since the power supply can output continuous current up to 120 % of the output current rating with the restricted ambient temperature range and current up to 160 % of the output current rating with the restricted output time tests can be conducted with a power capacity one rank lower. This feature also helps you cut equipment costs and save floor space.

Parallel or serial operation

Parallel operation enables multiple power supplies of the same model to operate in parallel, offering a large capacity of up to 8 kW (when five 1600-watt models are connected in parallel). In a serial operation, the voltage can be increased up to 160 V. (Note:*Parallel and serial operations cannot be done at the same time.*Serial operations are not possible for the M and H types.)

Up to 32 PWR series power supplies Can Be Controlled with One GPIB Address

The PWR series supports a digital communication function (TP-BUS) as its standard feature. When used with a power supply controller (PIA4830) to be purchased separately, the function enables up to 32 PWR series power supplies to be controlled using the GPIB or RS-232C interface. In addition, the sequence generation software (Wavy for PWR+PIA4830), also to be purchased separately, allows even those users who have no knowledge of any programming language to exert output control over the PWR series power supplies with sequence patterns of their choice and to read resultant data through the use of a PC.*Note: To control PWR series power supplies using PIA4830, you need ROM Version 2.20 or later in the PIA controller.
