Re-Vap™ Power Supply & Controller
MDC has taken advantage of its extensive knowledge of high frequency
solid-state switching power supplies by incorporating that technology into a
patent applied high-powered 3000 watt Re-Vap™ power supply. Tremendous
size and weight reductions are the result. With overall dimensions of 5" x 8"
x 13" and a total weight of 20-pounds, the power supply can be mounted
underneath the vacuum coating system just inches away from the high current
feedthroughs. The power supply is only one-eighth the size and onetenth
the weight of a typical 3000 watt resistive power supply. Two unique advantages include
higher power efficiency and floor space savings. Power efficiency is greater because the output cable
length is reduced with a resulting lower power loss. The Re-Vap™ controller is a half-rack width
display module displaying the current, voltage, safety interlock and status/operation
indicators. For automated coating processes, it may be connected to a rate/thickness controller for precise control.
Power can also be controlled through the front panel or with the hand-held remote control.
Re-Vap™ clamp, High Current feedthrough and Z-bar™ extensions
The Re-Vap™ positive clamping method is universally designed for heavy use
and quick-change capability. Thumbscrews are provided for fast installation
of boats or filaments. Air-side clamping uses silver-plated battery clampstyle
hard copper connections designed for maximum surface contact and high current carrying
capacity. The Re-Vap™ high current 3/4-inch feedthroughs are rated at 600 amps. It
uses high purity alumina ceramic as the dielectric material, which is hermetically
sealed to a flexible metal transition using vacuum grade braze alloys in a
vacuum brazing furnace. Additionally, a removable snap-on ground shield provides protection from
line-of-sight coating on exposed ceramic surfaces. Re-Vap™ feedthroughs are fitted with Del-Base™ baseplate
mounts in standard one-inch, 32mm or 34mm sizes for use in most vacuum coating
systems, including Balzers and Leybold systems.
Z-bar™ extensions are used in cases where normally an evaporation source
cannot be positioned because of spacing limitations. The modular Z-bar™
extensions allow you to maneuver your evaporation sources around fixed
equipment inside your vacuum coating system. Its versatility allows you to
use them singularly or in multiples for those hard to reach locations.
