The PSW-Series are single output from 360 Watts to 1080 Watts, programmable switching DC power supplies. OVP, OCP, OTP protect the power supply and loads from unexpected conditions. Remote sensing adds an extra level of precision by compensating cable losses between loads. The bright LCD with simultaneous parameter outputs allows effortless operation.

Self-test and software calibration features also reduce maintenance efforts. SCPI commands and LabView driver access through the RS-232C or the optional GPIB interface allows remote control and ATE software development. Modular architecture, dedicated rear-panel output, and the 19-inch 4U rack mounting option ensure that the PSH-Series is optimized for large systems.

The PSU-Series is a single output programmable switching DC power supply covering a power range up to 1520 watts. This Series of products include five models with the combination from 6 Volts to 60 volts rated output. As the PSU-Series can be connected in series (2 units) or in Parallel for maximum (4 units), capacity of connecting multiple PSU-Series for higher voltage or higher current output provides a broad coverage of applications.

The C.V. / C.C. priority selection of the PSU-Series is a very useful feature for DUT protection. The conventional power supply normally operates under C.V. mode when the power supply is turned on. This could bring inrush current to the capacitive load or current-intensive load at the power output ON stage. Though the current becomes stable after the C.C. mode is activated, the current spike occurred at the C.V. and C.C. crossover point may possibly damage the DUT. At the power output stage, the PSU-Series is able to run under C.C. priority to limit the current spike occurred at the threshold voltage and therefore protects the DUT from the inrush current damage.

The OVP and OCP protections can prevent the DUT damage. Both OVP and OCP levels can be selected in the range of 10% to 110%, with the default level set at 110%, of the rated voltage / current of the power supply. The PSU-Series provides USB Host / Device, LAN, RS-232C with RS-485 and Analog Control Interfaces as standard. The LabView driver is available at the rear panel for external control of the power On / Off and the external monitoring of the output voltages and current.

The PSB-2000 series, is a high power density, programmable and multi-range output DC power supply. There are six models in the series including one power booster unit. The PSB-2000 series has the output voltage of 0 to 80V and 0 to 800V, and the output power ranges of 0 to 400 Watts and 0 to 800 Watts. Both series and parallel connections can be applied to the PSB-2000 series to fulfill the requirements of higher power output range.

The PSB-2000 series provides three sets of preset function keys to memorize regularly used settings of voltage, current and power that users can recall rapidly. The sequence function, via RS-232C, USB interface or optional GPIB interface, can connect with a computer to produce output power defined by the sequence of a series of set voltage and current steps that are defined by the computer. This function is often used to establish a standard test procedure for the verification of the influence on the DUTs done by swiftly changing operating conditions.

The PSB-2000 series protects over voltage and over current. The power supply output function will be shut down to protect DUTs when the protective mechanism is triggered to function. When conducting battery charging operation, the Hi-W mode of the PSB-2000 series will prevent reverse current from damaging the power Supply.

The PSB-2000 series provides analog control and analog monitor interfaces on the rear panel to control the output via an external voltage or to externally monitor voltage and current output status of power supply. The PSB-2000 can be rotated 90 degrees suitable for vertical or horizontal position to accommodate the ideal space utilization.
