EVD Evolution controller for electronic valves

Description

The EVD evolution series of controller for electronic valves is the latest step in the development of CAREL drivers for superheat control. Compared to the standard EVD, this instrument adds advanced functions and new user interface that makes it even easier to use and configure. 

Technical Specifications

• 2 Analogue Inputs: temperature probes
• 2 Analogue Inputs: ratiometric or 4-20 mA probes
• Use of ratiometric or 4-20mA transducers (the latter shared between several drivers)
• 2 Digital Inputs 
• Second digital input for defrost management 
• Power Supply: 24Vac
• Compatibility with valves: CAREL, Alco, Sporlan, Danfoss 
• Relay output
• LEDs for monitoring the main parameters 
• Power input 20VA

Advantages

• High usability
• Consistent energy saving compared to mechanical expansion valves
• Best equipment management via LAN integration
• Multilanguage graphic display, plug and play, with “help” on the various parameters
• Assisted start-up procedure (just 4 parameters)
• Copy parameters to other EVDs using the display
• Special function like transcritical CO₂ cycles through specific algorithm and pressure and temperature measure after heat exchanger
• Superheat control with auxiliary protectors
