How to work in NA7 demand switch
The NA7 power supply demand switch is an innovative product that reduces electromagnetic field interference generated by the power supply circuit.
Electricity has become an indispensable part of daily life, and the use of electricity is inevitably caused alternating electric fields and magnetic fields, electric fields and magnetic fields to the human organs have always been the theme of many international research. The "safety" level of the electric field and magnetic field is still determined, but many doctors and scientists now agree to reduce this level according to the principles of Alara (as much as possible).
The cutting-off power supply is proved to be the most effective, most economical solution to the residential (especially sleeping zone) to produce pollution through electric field or magnetic field. When you turn off the last lamp or appliance in the power supply continuous wiring, the NA7 demand switch installed in the insurance box will automatically interrupt the power and automatically connect to the lights when you open the light or appliance. Therefore, in the evening sleep, the EMF pollution produced by the electromagnetic field can be safely avoided.
Main advantages:
From the perspective of architectural biology, the most important thing is: our demand switch has unparalleled minimum residual fluctuations.
NA7 demand switch with VDE tag security certification.
Simple installation, easy to operate, easy to integrate into the circuit.
NA7 includes control lights and mesh filters to reduce power interference.
NA7 demand switch internal pressure sensitive power resistance is used to protect the power supply wiring line.
Product features
It can be reliably work with electrical equipment that does not require standby, such as dimmer, fluorescent lamps, energy-saving lamps, halogen lamps, computers, etc.
Emergency lights and baby indicators can work under power-down
Reverse and overvoltage protection
LED light display power disconnection
Residual ripple: <4 mV
LED indication of functional diagnosis, easy to install and operate
Best-selling demand switch
Installation Note:
The NA7 demand switch is only available for 230 V-50/60 Hz power networks, and a separate power supply loop requires an installation.
The NA7 demand switch conflicts with the power supply standby electrical appliances, it is necessary to form a loop alone.
Installation must be installed by the POWP certificate, not suitable for 110V power system
Installation instructions:
The power switch is turned off before the installation, connects the "N" zero line to the neutral interface, "L" fire line is connected to the demand switch output interface.
Tighted the power switch for testing, the demand switch power output is not connected.
LED light, green must be permanently glow, if "Autom Auto" is open, you must disconnect the load and turn off the power
Turn off the total power supply again, connect the protector to the output "L", turn on the power, can clearly hear the renewer switching, if yes, please check the connection and correct.
Unipolarity can achieve optimal protection, the smallest residual ripple is connected by a varistor PTC to a neutral interface
