High-efficiency, High-capacity Switching DC Power Supply (CV/CC) *Photo shows PAT40-200T

The PAT-T Series is a CV/CC auto-shifting switching DC power supply featuring excellent efficiency and low noise due to a soft switching system design. The PAT-T series is equipped with state-of-the-art high-density packaging technology allowing for extremely high power capacity with a vastly reduce chassis size and weight. A built-in “power factor correction circuit” greatly reduces noise while supressing harmonic currents for an optimal electronic test environment. Power reception and distribution modules have been simplified resulting in lower power consumption and an overall decreased cost of ownership.

Guaranteed continuous operation at ambient temperatures as high as 50°C make the PAT-T the perfect power supplies for extremely demanding environments even under full-load.

The PAT-T is equipped with an intuitive, user-friendly display panel supporting standard RS232C digital interface as well as external analog control, monitor output and status output connectors allowing for control via computer or sequencer. USB, GPIB, or LAN (LXI) digital interfaces are also available as a factory option. The PAT-T power supply is an extremely versatile test instrument easily incorporated into any test system or used stand-alone.

Well-developed communication interface
RS-232C (standard equipment), USB/GPIB/LAN (LXI) options supported!

Commands are compatible with both SCPI and IEEE 488.2 standards. Free measurement instrument drivers (available on website) are available for control via Excel VBA and LabView alongside proprietary Kikusui sequence creation software, “Wavy for PAT-T,” allowing for easy creation and editing of customization of user-defined waveforms. The digital LAN interface is compliant with LXI (LAN eXtentions for Instrumentation), meaning that the PAT-T can easily be controlled and monitored from a remote browser.

Soft switching system

The PAT-T power supply circuit system skillfully utilizes resonance when executing power device switching when the voltage or current is at zero. This allows the unit to operate without switching loss or transient crossover of voltage and current. Switching that occurs at 0V is known as “zero voltage switching” (ZVS), while switching at zero current is referred to as “zero current switching” (ZCS). With conventional power supply circuits, problems such as increased power loss and diminishing efficiency occur when switching speed increases. However, a soft-switching system utilizes highly efficient power supply circuits that reduce heat loss and allow for for smaller circuitry, resulting in compact chassis size as well as minimal noise generation.

Soft switching system

Power factor correction circuit

The power factor (PF) values indicates the efficiency of an AC circuit, referring to the ratio of effective power to apparent power. The closer the power factor is to 1, the more efficient the equipment (circuit) is in its electrical power usage. Incorporating a power factor correction circuit corrects AC voltage and current phase differences (waveform deviations causing reactive power), improving electrical power efficiency. Specific advantages include the following:

  • Increased energy efficiency.
  • Downsizing of power reception and distribution modules.
  • Improved power supply environment.
  • Reduces transmission loss.
  • Vastly reduces noise emissions.

40 V, 200 A DC at full-load with 85% efficiency.

Improving the power factor from 0.6 to 0.95 reduces required input power by approximately 40%. A high power factor saves energy!

Increased Capacity via Parallel Operation: Max. 40 kW, 2000 A

Parallel operation up to five units of the same model!

Up to 5 units (2 units for PAT850-9.4T, PAT1000-8T, and PAT1500-5.3T) including the master unit can be connected in parallel. The connection is a one-control parallel operation, and the panel of the master unit can control and display the entire system (Maximum display: Single unit’s Rated current x number of units in parallel). Current display on the slave unit is possible only when the STORE switch on the main unit panel is pressed. Note that the optional Parallel operation cable PC01-PAT is required for connection, depending on the number of units connected. The 8kW type 400V input models (PAT20-400T/PAT40-200T/PAT60-133T/PAT160-50T) and the 4kW type are not supported.

Series operation up to two units of the same model!

Up to two units can be connected in series for 8 kW (PAT20- 400T, PAT30-266T, PAT40-200T, PAT60-133T, PAT80-100T, and PAT160-50T) and 4 kW types. However, master-slave operation is not supported. The sum of the output voltage between the two units is supplied to the load.

Convenient, Intuitive, and Safe

4 kW types operable with single-phase 200 V input.

The current is limited to approximately 75% of the rated value with a power limit of 3 kW.

4 kW types operable with single-phase 200 V input.

CV, CC priority starting function*

The PAT-T can be set to start up as either a constant voltage (CV) power supply or constant current (CC) power supply when the output is turned ON. CV priority mode is used during constant voltage, while CC priority mode is used during constant current for smooth startup without overshoot.

CV, CC priority starting function*

External analog control function

Output voltage can be controlled by an external voltage (Vext) of 0 V to 10 V or an external resistance (Rext) of 0 kΩ to 10 kΩ. FAST mode* allows for direct control of external voltage (without passing through CPU), removing any delay between Vext and changes in output voltage.

DC-DC Converter Evaluation Test System

Power Semiconductor Evaluation System

This is used to measure temperature change of semiconductors by starting up a large Current at high speed, for example, in transient thermal tests of semiconductors. The PAT-T series of high-capacity switching power supplies alone can start up in several tens of milliseconds*, and when used with the PLZ-5W series of electronic load devices, even higher speeds are possible. Start-up in a few milliseconds is possible by special order. Please contact us if you wish to start up in a few ms.

Power Semiconductor Evaluation System

Battery Evaluation Test

Although high-speed operation cannot be achieved using only the PAT-T high-capacity switching power supply, the fast-response unipolar power supply system can be suplemented by connecting with the PLZ-5W series electronic load in series and parallel. This makes it possible to flow current while synchronizing the charge and discharge current patterns for a battery at high speeds.

Battery Evaluation Test

Fuse Rupture Test

For fuse rupture tests, DC power supplies with high speed CC control is absolutely vital. Although it is normally quite difficult to achieve such high speed control with only a DC power supply, the addition of a PLZ-5W electronic load makes high speed current control possible. With the PLZ-5W, fuse rupture tests that adhering to standards such as the JASO D612 are made possible. These tests include voltage drop tests, transient current cut-off tests, rupture time tests, step energization tests, and breaker capacity tests.
