No Stock: more on 6/1

An isolated dc-actuated power cord for controlling power to 120vac appliances from a microcontroller I/O pin (3-12vdc, 3-30ma).

FEATURES
  • Solid-state triac switching; longer service life, no audible contact click and faster response time.
  • Controls power to loads up to 300 watts, non-inductive, with a 3vdc (3ma) to 12vdc (30ma) steady or pulsed control signal.
  • Provides random (not zero-cross) switching suitable for 120vac phase-control dimmer applications for incandescent and LED light strings. Use the ZeroCross Tail to safely obtain the necessary zero-crossing sync pulse. Arduino sample sketch or variable dimmer . Video demo.
  • Connects directly to I/O pin of the Arduino, Raspberry Pi, Beaglebone or other 3.3 or 5 volt MCU. 
  • 5300vrms isolation between ac circuit and signal connection.
  • Built-in LED indicates status of control signal.
  • No exposed 120vac voltages and no dangerous 120vac wiring required. Can be installed by non-technical users:  Instruction sheet .
  • Plugs into standard 120vac 3-prong household outlets, power strips, and extension cords.

SPECIFICATIONS
  • AC input: NEMA 5-15P Plug, standard 120vac with ground.
  • AC output: NEMA 5-15R Receptacle, standard 120vac with ground.
  • Load capacity: 120vac, 300 watts maximum continuous load, non-inductive.
  • Switching device: Solid-state triac.
  • DC input: 3-12vdc (3-30ma), terminal block accepts #14-30 AWG wire..
  • Operate times: Suitable for 60hz phase control of incandescent and LED light strings.
  • DC to ac circuit isolation: Optically isolated >5,000vrms.
  • Indicator: LED indicates when dc side is energized.
  • Protection: AC side protected with 150vac MOV. DC side is transient free.
  • Mounting: Two #6 screws or free standing.
  • Environment: Indoor use only.
