Electrical control panel AKO-16526 + EEV controller 100–240V AKO Spain

The AKO-16526 controller can be used for the direct control of a PWM-type electronic expansion valve (for step-type valves, an external driver is required). The controller instructs the driver on the valve opening based on the evaporator outlet pressure and temperature to achieve the superheat value set in the Sh parameter. Optimal superheat increases evaporator efficiency.

This panel can manage complete refrigeration systems for both cooling and freezing applications, or it can be used as a sub-panel in units with central systems (multi). It controls all functions, including the EEV, such as:

• Evaporator heaters
• Compressor
• Solenoid valve
• Crankcase heaters
• Single-phase evaporator fans
• Air/hour or electric defrost
• Chamber light switch

It can also control two evaporators with a single compressor via a third sensor. Supports Bluetooth connection and remote control via mobile device ("sharing"), and data logging via the CAMM MODULE (optional). 

Note: SELD-DRIVE is not available (only on model AKO-16526A).
