Features
Esy 1 is a tension speed controller used with asynchronous single-phase motors mounted on heat exchangers.
TECHNICAL DATA
Single-phase power supply:1ph+N+PE 230V ± 20 % – 50/60Hz.
Working temperatures: -10°C ÷ 50°C.
Box in thermoplastic UV protected material with protection class IP56.
Input by external signal or transducer: 4-20mA; 0-5V; 0-10V; NTC 10KOhm 25°C;
Regulation mode MASTER “P” (temperature or pressure probes) or SLAVE (0-10V)
Possibility of connection for temperature probes (default) or pressure probes.
Working parameters selectables with trimmers:
- Max Out : Max output limit RPM
- Min Out : Max output limit RPM
- SP : Main Set-Point 1
- SP adj. : Set-Point 1 fine adjustment
Special Functions selectables with trimmers:
- J1: Direct (DEFAULT) /Inverse;
- J2: Speed at set-point Max (Default) / Min;
- J3: Start regulation Mode Start Vac (Default) / Min speed;
- J4: Output for Extra Slave Power 0-10V (Default) / PWM 4.20mA.
N°1 output 0-10Vdc/PWM for slave unit.
Led for power supply.
Led for Setpoint higher than input signal.
