The units are 33% smaller and 40% lighter than the previous generation (ZUP series) and similar products, thus providing a 49% increase in power density. The standard models are only 3.27 in. high by 2.76 in. wide, so up to six units can be installed in the optional 19 in. rack housing; blanking plates are available for unused slots. Options for front panel output-jacks and multiple-unit housings are available for bench-top applications. Later this year, 200-W, 600-W and 800-W models with the same dimensions will be added to the series. The units have comprehensive front panel controls with individual rotary encoders for output current and voltage, and access to power supply settings such as OVP level, start-up modes, remote control and monitoring parameters. Separate four-digit volt and current displays are provided along with function/status LEDs, pushbuttons for output preview, output on/off, fine/coarse and other features. The supplies offer arbitrary function generation, and up to six pre-programmed functions can be stored, making them suitable for automotive or laser simulation tasks. The supplies feature a very fast command processing time, output sequencing and two programmable output pins that, for example, could be used to control isolation relays. All models can operate in either a constant-current or constant-voltage mode from an 85 to 265 VAC input.
