The KIKUSUI PAT-T Series is a high-capacity switching DC power supply for constant-voltage and constant-current testing, with current 4 kW and 8 kW models covering output voltages from 20 V to 850 V.
The KIKUSUI PAT-T Series is a high-capacity switching DC power supply designed for constant-voltage and constant-current testing where substantial DC power, high current, or high output voltage is required.
Current PAT-T models provide 4 kW or 8 kW of rated output power, with voltage ratings ranging from 20 V to 850 V and current ratings up to 400 A per unit. This broad model selection supports applications ranging from high-current automotive electronics and motors to power semiconductors, DC-DC converters, inverters, and high-voltage component evaluation.
The PAT-T uses a soft-switching topology for reduced output noise and high efficiency and incorporates a power factor correction circuit with a typical power factor of 0.95. RS232C is standard, while LAN, USB, and GPIB are available as factory-installed interface options for automated test and system integration.
Current PAT-T models provide either 4 kW or 8 kW of rated DC output, supporting demanding component, automotive, power-electronics, and industrial test systems.
The current lineup extends from low-voltage, high-current models to 250 V, 350 V, 500 V, 650 V, and 850 V models for higher-voltage DC evaluation.
Constant-voltage and constant-current automatic crossover operation is combined with a soft-switching power stage designed for high efficiency and reduced output noise.
An integrated power factor correction circuit provides a typical power factor of 0.95 at rated operating conditions, helping reduce input-current and power-distribution requirements.
RS232C is standard, with LAN, USB, and GPIB available as factory options. External voltage and resistance programming supports integration into automated and specialized test systems.
Supported PAT-T configurations allow same-model series or parallel connection for increased voltage, current, or system power, subject to model-specific connection limits.
