Vacuum-System Equipment Hub
Power Supplies
& Valve Controls
Explore the power electronics, valve controls, sequencers, interlocks and control hardware behind vacuum coating systems—from high-voltage electron-beam supplies and sputtering power to pump logic, chamber valves and custom control panels.
Power, Sequence & Protection
The electrical layer between the process recipe and the vacuum hardware
Vacuum coating systems depend on more than one power supply or valve box. High-voltage, RF, DC, thermal and ion-source power must match the connected load, while valve controls, pump sequencers, cooling permissives, pressure signals and safety interlocks coordinate when each device is allowed to operate.
This page helps identify the equipment and the connected architecture. It does not replace YTI’s focused pages for component-level repair, complete refurbishment, control-system modernization, field troubleshooting, electronic stocking or custom panel fabrication.

Power Conversion
High-voltage, RF, DC, AC, SCR, transformer and switching sections that convert facility power into the output required by the source or load.
Output & Device Control
Setpoint, current, voltage, emission, sweep, strike, ramp, shutter, valve-position and device-enable functions that command the equipment.
Sensors & Feedback
Current and voltage feedback, pressure switches, gauges, limit switches, flow and temperature devices, valve-position signals and deposition feedback.
Sequence, Logic & Interlocks
Pump-down logic, valve sequencing, pressure permissives, cooling checks, door and chamber safeties, alarm handling and operator protections.
Load & Chamber Interface
The connected source, pump, valve or process device plus cables, feedthroughs, connectors, cooling, vacuum conditions and chamber integration.
Selection & Integration
What determines the right power or control configuration
Connected Load
The source, cathode, heater, ion device, pump or valve must match the supply’s operating range, dynamic behavior and protection requirements.
Voltage, Current & Power
Input and output voltage, current capacity, phase, frequency, maximum power, regulation, ripple and duty cycle shape compatibility.
Control & Feedback
Local or remote setpoint, analog or digital interfaces, current and voltage feedback, rate control, status contacts, enables and fault outputs.
Valve Type & Sequence
Pneumatic or electric actuation, normally open or closed state, limit feedback, pressure sequence, fail-safe behavior and pump-protection logic.
Grounding, Cooling & Environment
Grounding, shielding, cooling-air or water requirements, contamination, heat, cabinet ventilation, cable routing and high-voltage clearances.
Cabinet, Wiring & Documentation
Physical rack or cabinet fit, connector pinout, wiring condition, labels, manuals, drawings, spare parts and long-term serviceability.
