Description

Digital asymmetry and voltage drop sensor ZAMEL CAM-11. The True RMS digital voltage measurement ensures measurement accuracy even with distorted waveforms. Delayed deactivation and voltage hysteresis eliminate frequent disconnections. Two-module housing, mounting on TH 35 DIN rail. Protection against phase loss and resistance to short-term voltage drops. Relay output - one switching contact with a maximum load of 16A.

The voltage asymmetry sensor CAM-11 is used to protect devices powered by a three-phase network (e.g., motors). The asymmetry threshold value is factory set to 55 V. The sensor also protects against symmetrical voltage drop by disconnecting the relay if the voltage in any phase falls below 150 V. The device is powered by any phase, meaning that the presence of voltage in one phase is sufficient for it to be fully operational.

The 4-second deactivation delay and voltage hysteresis make the sensor resistant to short-term voltage fluctuations.

Application: The voltage imbalance sensor protects the motor from operation in case of a power outage, allowing it to operate only at the appropriate voltage level.

Installation:

  • Safely disconnect the power supply circuit.
  • Check that there is no voltage on the supply wires.
  • Install the CAM-11 device in the distribution board on the TH 35 rail.
  • Connect the wires to the terminals according to the wiring diagram.
  • Activate the power/measurement curves: L1, L3, N.

Indications:

  • Nominal supply voltage / supervision: 230 / 400 V
  • Nominal frequency: 50 / 60 Hz
  • Nominal current consumption: 12 mA
  • Voltage indications on individual phases: LED - yellow, green, red.
  • Relay contacts: 1NO/NC - 16 A / 250 V AC1
  • Number of connection terminals: 8
  • Cross-section of connection wires: 0.2 - 2.50 mm2
  • Operating temperature: -20 - +60 °C
  • Operation position: any
  • Enclosure mounting: TH 35
  • Protection level: IP20
  • Overvoltage category: II
  • Pollution degree: 2
  • Dimensions: 90x35x66 mm
  • Weight: 0.11 kg
