GW Instek debuts the PSB-1000 series, which is a single output channel, programmable and  multi-range DC power supply. The series comprises 400W models: PSB-1400L(40V/40A); PSB-1400M(160V/10A), and 800W models: PSB-1800L(40V/80A); PSB-1800M(160V/20A). The maximum voltage output of 320V can be realized by placing 160V units in series connection. By connecting PSB-1800Lunits in parallel, the maximum current output of320Acan be achieved. The PSB-1000 series is a bench-top power supply featuring user friendly interface, which can clearly display setting conditions and measurement results via LCD display and menu-typed functionality selection without referring to the user manual. All settings can be done by functionality keys, numerical keys, and speed dial keys. The30Aoutput capability from the front terminal of the PSB-1000 series can better meet the requirements of laboratories and scientific R&D units.

The PSB-1000 series features user friendly menu-typed functionality interface and its built-in functionalities can better meet industry's application requirements. Both front panel and rear panel output terminals of the PSB-1000 series facilitate researchers to access power output conveniently. The display panel adopts menu-typed functionality selection to help users quickly familiarize with settings and operation that is extremely suitable for on-site engineers and R&D engineers who deal with complicated functional setting requirements. The Bleeder function helps rapidly bleed internal capacitors to avoid potential danger of discharging electric charge. For battery's charging applications, users can set Bleeder to Disable to avoid impact on battery charging applications. The I/V Control function, based upon DUT's requirements, sets rise and fall speed of voltage and current respectively to effectively reduce surge voltage and current output as well as to measure DUT characteristics. The CC priority output mode can be utilized to protect diode characteristic load and LED load from being damaged by inrush current. Sequence Function (SEQ), via editing Excel charts and uploading them to the instrument, automatically executes the required output waveforms to meet the requirements of related regulations and tests. The automatic execution of the sequence function is often applied to planning a set of continuous voltage variation to assess DUT characteristics. For instance, producing a series of voltage variation output to test impact on automotive fans is one of the reliability test applications. Power On Configuration allows users to select previously set SEQ to carry out automatic execution as soon as power is turned on. For production lines demanding sequential power supply output application requirements, tremendous time can be saved by this function, which exempts users from resetting sequential power supply when power is turned on every single time. Voltage Trigger allows users to set pulse signals for leading edge threshold and trailing edge threshold. VOLT TRIG can be applied to ATS by providing output time for working voltage via BNC adapter. The Output Delay function facilitates users to respectively set action time for power output on and power output off for multiple sets of PSB-1000 so as to realize sequential power output applications.

The PSB-1000 series is equipped with multi range power output capability providing fourfold rated power output to meet customers' flexible application requirements. The models and operating area of the entire series are as the following chart:
