Solder-free,7.62 terminals for input terminals. Blue 301 terminal block for high frequency AC output, 7.62 terminal block for DC output. Voltage can be at , through the jumper cap, no need to solder. Large output power, if there is a fan cooling, this board can output 200W power using double-sided circuit board. AC output can be connected to multiplier rectifier, or pure resistive load High frequency AC output: only suitable for resistive loads, such as ordinary household incandescent bulbs ( bulbs), ordinary soldering irons, or connected to a doubling rectifier circuit, measure the output voltage do not measure this output, because these voltmeters are designed to measure 50Hz household voltage, not high frequency voltage, there be a huge measurement error. DC output port: you can use a multimeter DC gear to measure the voltage, you can take the switch power class load (marked input voltage of AC100-240V voltage appliances are available), resistive load. 150W inverter battery DC12V step-up to AC220V step-up transformer power conversion circuit board. Switch: The black line on the board is the switch, used to control the presence or absence of high voltage output. Input voltage: 12V, limited low input voltage 8V, limited high input voltage 14.8V. as this board does not have input fuse, please add your own fuse, recommended to add 15A fuse (lithium battery power supply and switching power supply, DC power supply class power supply, this type of power supply lead to tube overheating burned), the output is not regulated, the input to sufficient power (current), otherwise it is easy to burn out The output voltage is not regulated. Output voltage: 110V 200V 220V 280V Output waveform: high frequency square wave or DC (unfiltered) Output power: 150W (more than 100W please add fan cooling) No-load 12V terminal current:250mA Operating frequency:27KHZ Protection: No protection, please add your own fuse for use Features: no welding, input terminals using 7.62 terminals, high frequency AC output using blue 301 terminals, DC output 7.62 terminals (directly loosen the terminal screw at the top, insert the wire, tighten the screw can be) Voltage can be at , through jumper caps, no soldering required Output power is large, if there is a fan cooling, this board can output 200W power using double-sided circuit board. AC output: can be connected to multiplier rectifier, or pure resistive load Output voltage: already marked on the circuit board Color: As Shown Material: Metal+Plastic Package Contents: 1 * module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
