 PL303QMD-Dual-0-30V-0-3A-LXI-RS232-Analogue-Power-Supply

PL303QMD Dual 0-30V/0-3A LXI/RS232 Analogue Power Supply



This Dual analogue Power Supply achieves an exceptional power density for a linear regulated power by offering up to 90W from a ¼ rack 3U sized casing.

Up to four single output units can be fitted into one rack width. Alternatively, any combination of singles and duals can be used - as in the example shown.

The TTi RM450 rack mount (shown) is 4U high and incorporates limited ventilation space above and below the power supplies. Blanking plates are provided for unused positions.

This gives it an unusually small bench footprint taking up less space on a crowded bench. For rack-mount application, up to four units can be mounted into a single slot. Despite its small size and linear regulation, the TTi Dual analogue Power Supply produces relatively little heat through the use of an advanced phase controlled pre-regulator. This gives it significantly higher energy efficiency than conventional linear regulated designs, particularly when supplying lower voltages.

The internal heat-sinks use fan-assisted convection cooling in order to remove the heat with minimal fan noise.
The ultra-compact rack-modular sizing makes it ideally suited to rack mounted system applications, while its user-friendly manual controls are retained for bench top applications.

To meet the varying needs of todays engineers, a comprehensive array of interfaces is provided. RS-232, USB and LAN (Ethernet) with LXI support are provided as standard. An additional GPIB interface is also optionally available.

Each of the digital bus interfaces provides full control of voltage, current, and output On/Off, plus read-back of voltage, current and status. The interfaces are at ground potential and are opto-isolated from the output terminals.
