Rockville RFC50F 50 Farad Capacitor Blue Voltage Display. ESR (Equivalent Series Resistance): 0. 015 ohm @ 120Hz, 25°C. 50 Farad Digital Hybrid Capacitor with Blue Illumination.
Blue illuminated window with light that blinks to the beat of the music. Black wire mesh cover. Warning tones for reverse polarity connection.
3-Digit, super bright LED voltage meter. Automatic sleep status when volume is low. Operating Voltage: 10 - 16V DC.
Surge Voltage: 20V DC. Voltage measure accurate to +/- 0. 1VDC. Capacitance tolerance: +/- 10%.
Over-voltage protection circuit automatically alarms when the voltage above 17. 5V or under 10V. Unit dimensions (Inches): 10. 91” L x 6. 38” W x 2. 56” H..

It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C)..
The impedance become small, and we can then measure the true series resistor value..
Using this theory, we can measure the capacitor is bad/ damaged or good in condition..
Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test..
During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not..

...t circuit for long time). Plus, when input and output is common grounded, no-load CV output constant voltage,CC output constant current.
Adopting 75V / 80A large current dual MOS tube designed step-down board, Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. Large current 30A connection screw terminals, more convenient to install.

The new-designed U.S. Solid battery spot welder is equipped with two super capacitors for energy storage and stable power source for pulse spot welding. Comparing to the traditional AC spot welder, it has no interference to the electric circuit and no more tripping problems. The max pulse welding power can be up to 11.6 KW, ensuring you a reliable welding effect..
The portable welder has a small size and light weight, allowing for easy transport while still adopting 100-240 V wide-voltage input for use anywhere you need. Comparing to the traditional big size and heavy spot welding machine, it is smaller and lighter, but more powerful and reliable..
Equipped with the 70B mobile welding pen, 73S handle-push welding arm and ‘AT/MT’ two welding modes, you can finish the welding work easily and efficiently, the welding spot is nice and elegant. The capacitor energy-gathered pulse technology and low power consumption enable you to use the machine for 12 hrs efficient welding work with no heating problems..
The pulse welding power can be set up conveniently via two adjusting buttons(0-99 range), which is shown directly on the panel LED screen(welding power/capacitor voltage/actual welding current are displayed). The maximum welding energy is 119 J, 0.....
