DC Current Switch,Current Sensing Relay DC Current Sensing Switch 0-300A Amp Sensor Monitoring Relay D366

  • Basic Function:When the piercing current exceeds the set value, the output switch will act Automatically reset when the piercing current is less than the set value..
  • Set threshold: set the threshold when the perforation current exceeds the threshold, the relay will work, and when the perforation current is lower than the threshold, the relay will reset.
  • Indicator light: the indicator light is off when there is no current, the green light is on when the current is lower than the threshold, and the red light is on when the current is higher than the threshold.
  • Delay adjustment: power-off delay can be set from 0 to 99 seconds, clockwise to increase and counter-clockwise to decrease.
  • Detection range: 0-50A, [email protected] AC/DC contact capacity.

  • Broad (Wide) / Narrowband (Narrow) Selectable.
  • Recommended Accessories: Pair UV-25X4 with the Nagoya TB-320A Antenna (and RB-50 Magnetic Mount) for easy installation. The PC04 FTDI Cable is recommended for easy computer programming.
  • Dual Watch monitoring VHF/UHF and 220Mhz: The 220 MHz band antenna lowpass filter is switched with a relay and the 2 meter lowpass filter and 70 cm highpass filters are switched with PIN diodes - resulting in a audible relay switch noise when monitoring 220MHz with VHF/UHF simultaneously. A relay that completely isolated the 220 MHz RF filter won't impact the RF performance of the 2 meter/70 cm bands. If monitoring multiple 220MHz or VHF/UHF simultaneously the relay is not heard or used..
