Reviews Voltage Controlled Oscillator

HiLetgo 0.1-500MHz AD831 High Frequency RF Mixer Drive Amplifier Module Board HF VHF/UHF

【SCR Controller】This item has new two-way large power silicon controlled rectifier and the current can be up to 80A, which is a good solution to over-current of electric stove wire caused by low resistance during cooling..
【1000W】It can easily adjust the output voltage on a scale of 0-100% (nonlinear) to power electric device. It can be used as power supply for large electrical devices of less than 10000W, enough for household appliances or for small factory..
【Heatsink】Designed with large and thick heat sink that would enhance heat dissipation. Voltage regulator has wave voltage absorbing circuit and effective protects large power silicon controlled rectifier, longer service life and more durable..
【Suitable for】Could be widely used as heat controller on electric stoves, water heaters, light dimmer on lamps, speed controller on small motors, or temperature controller on electric soldering iron, etc..
【Note】AC input, AC output, output voltage is lower than(or equal to) input voltage.
voltage can be adjusted only when connected to load.
