Compact supply is powerful but really cool
Delta Tau has unveiled a new compact discrete power supply, called the Quad PSU, that not only reduced cabling for the company's new Geo Brick LV IMS-II, but also provides reliable power for up to four separate Geo Brick units in a single rack mounted device.
The power supply unit is a low profile 1U blade type configuration with three power supplies plus a Regen unit. It has a u niversal Input (85 - 265VAC) with built in power factor correction. Because of the highly efficient nature of the switch mode power supplies used it runs at a cool 10 degrees above ambient at full load.
One 1600W 48V and two 150W 24V supplies provide the power to the Geo Brick LV IMS-II motion controllers supplying the Motors, logic supplies and user I/O. These supplies deploy the latest internal ORing MOSFET and Current Share devices to deliver the highly compact efficiency required by today's beamline engineers.
The full specification of the 1600W output supplies is as follows:
