EpiTech has developed a new line of power supplies designed for the unique needs of heated viewports. These innovative & flexible products offer power up to 400 W and have unique capabilities such as Ethernet and serial comms standard, customizable ramping, smart interlocking features, and real time display of output voltage and current.

Thoughtful Features Designed for the End User

EpiTech solutions are designed by MBE engineers to specifically address the challenges and frustrations experienced by MBE engineers in the day-to-day operations of their MBE systems.

• Type K thermocouple input for temperature monitoring and recording

• Enable button on the front panel for easy disabling of the power supply

• Two presets, low and high, can be customized and are easy to access from the home screen

• Touchscreen makes configuring interlocks and communications easy

• Reliable and efficient power factor correcting and Mil-Spec’d DC power supply

• Long life enclosure fan; MTBF of 24.5 years!

• Output power of up to 400W

• Real-time voltage and current displayed on power supply diagnostics screen

• Cool room air enters through front vents, exits into rack

• Comms — EI-Bisynch and Modbus RTU over serial (RS-422) and MODBUS TCP

• Universal voltage input (100-240VAC)

Innovative Interlock Features For Improved Reliability

Interlock 1 failure initiates a controlled ramp down

EpiTech's smart interlock control for interlock 1 allows for the MBE grower to have interlock protection for the heated viewport, while also ensuring the viewport temperature does not change so quickly that it jeopardizes the structural integrity of the viewport.

interlock 2 failure initiates a ramp to preset low

The purpose of interlock 2 is to allow the MBE grower to water cool the port containing the heated viewport and interlock that water cooling. If the water flow interlock detects a cooling failure, the SmartHeated Viewport Power Supply will automatically ramp down to preset low, which can be programmed for a power level that is safe for operation without water cooling.
