Pressure relay EVAK DPC/10

Digital Pressure Switch EVAK DPC for Pump Control

EVAK DPC is a high-precision, next-generation intelligent pressure switch designed for pump system management. Unlike mechanical switches, this digital device provides full control over water parameters, protects the pump from failures, and allows system settings with a precision of up to 0.01 bar.

Application

The switch is used for the automation of surface and submersible pumps. It does not just start and stop the pump based on pressure settings but also performs protection functions, replacing several devices at once (switch, pressure gauge, and dry-run protection).

Key Advantages

• High Precision: The electronic sensor eliminates inaccuracies typical of mechanical springs.
• Dry-Run Protection: Automatically shuts down the pump when water is absent, preventing motor overheating.
• Auto-Restart Function: In case of protection activation, the device will automatically check for water at set intervals.
• Frequent Start Protection: Prevents pump failure in case of system leaks or hydrophone tank malfunction.
• Digital Display: Allows real-time monitoring of the current system pressure.

Technical Specifications

• Regulation Range: from 0.01 to 10 bar
  
• Power Supply: 115 - 230 V.
• Maximum Current: 12 A.
• Connection: G 1/4" (male thread).
• Protection Class: IP 55.
• Maximum Liquid Temperature: +65°C.

Main Settings

The device is configured using the buttons on the front panel:

1. P-ON (Cut-in): Pump start pressure.
2. P-OFF (Cut-out): Pump stop pressure.
3. Delayed off: Turn-off delay to prevent water hammer.
4. Auto-reset: Setting intervals for automatic restart attempts.
