Kikusui AC & DC Power Supplies, For Electronic instrument

The PAT-T Series is a constant voltage/constant current, auto-shifting, switching DC power Suppliers. It features a soft switching system that offers greater efficiency and lower noise. At the same time, it makes full use of high-density packaging technology to reduce the unit’s size and weight. The chassis is the standard rack width (430 mm) and is about 130 mm (3U) high and 550 mm deep. The output power is 8 kW. Compared to series regulated products of the same capacity, it is about 1/6 the volume and 1/7 the weight. While offering a high output of 8 kW despite its small cabinet size, it also features a “power factor correction circuit.” With a high power factor of 0.95, it improves the power environment (suppresses harmonic currents) and also greatly contributes to "energy saving," as exemplified by it's simplified and miniaturized power reception and distribution modules, and overall lower power consumption. Furthermore, an optimized heat radiation design will make operation guaranteed at ambient temperatures of up to 50 °C. It can thus be deployed in demanding applications where it must provide full-load, continuous operation despite high ambient temperatures. The layout of the operation/display panel is simple and intuitive and has been designed with viewability and usability in mind. An RS-232C interface is provided as standard together with external analog control, monitor output, and status output connectors, enabling control from an external computer or sequencer. In addition, GPIB or USB interface can be equipped as a factory option. The unit can either be used in a standalone configuration or can be incorporated into a test system.
Features:

• 4 kW type can operate even with single-phase 200-volt input. (However, current is limited to about 75% of rated value.)

• Standardly equipped with the RS-232C interface.

• Supports USB/GPIB/LAN interface.(Factory option)

• Controllable from Excel VBA and LabView with measuring instrument driver. The driver can be downloaded free at our web site.

• Capacity can be expanded through parallel operation (up to five units of the same model).

• Equipped with reliable output ON/OFF delay function during sequence operations.

• Memory function (three sets of voltage/current)

• Voltage/current monitor output

• Status signal output

• Remote sensing function

• Protective functions (shutdown, as well as protection against overvoltage, overcurrent, overheating, input phase interruption, fan malfunction, sensing, and bleeder circuit overheating)

• High noise resistance (for reassurance during car electronics testing)

• Good maintainability, including easy fan replacement

• 3-phase 400V input available (8kw type)

• The LAN interface applies to the LXI (LAN eXtensions for Instrumentation). If that interface is used, it is possible to control and monitor the power supply from a browser.

Applications:

• Lifetime testing of headlights, etc

• Performance and endurance testing of inverters for use in high-capacity air conditioners and motors

• Performance and endurance testing of brushless motors for use in EPS, MG, and SG units

• Performance testing of IPM, IGBT, and other power modules

• Performance testing of starter motors
