Power board for tattoo removal devicesND-YAG / Q-SWITCH POWER
The power board of Q-switched ND-YAG tattoo removal and carbon peeling devices. It builds up the high-voltage energy the lamp needs, manages the trigger timing and safely discharges that energy when the device is switched off.

Product capability
Power electronics engineered for system integration.
Charging, triggering and safe discharge on one board.
ND-YAG and Q-Switch are not separate products; they are two parts of the same device. This board covers both the energy and the lamp-trigger side of a tattoo removal device.
The open-frame board seen from above. Charging stage, trigger circuit and the contactor that manages the energy path share one chassis.

Connections and terminals
How does it connect to the system?
The board ships open-frame; the connection layout is planned together, around the internal design of your device. The numbers mark the connection zones on the board and match the numbers in the connection diagram below.
1234- Mains input (line / neutral)220 V AC supply. Line (brown) goes to the L terminal and neutral (blue) to the N terminal; the two must not be swapped. As the board is open-frame, protective earthing runs through the device chassis.
- Control interfaceLink to the device controller. Charge command, pulse energy reference, simmer, lamp triggering and Q-switch timing all run over this line; charge and ready states are read back through the same interface.
- Capacitor connection (CAP+ / CAP−)The capacitor supplied with the board is charged to high voltage through these terminals. It is a high-voltage component: complete discharge must be verified at device level before service.
- Applicator outputThe switched output feeding the handpiece. On each pulse the capacitor discharges into the flash lamp through this terminal and the shared negative terminal.

The values in this table come from three sources. First, the ratings of the components actually used in the product: the pulse capacitor, the contactor that switches the energy path and the input class. Second, quantities calculated directly from those ratings, such as the energy a 100 µF capacitor holds at 1400 V. The capacitor is a film type rather than an electrolytic precisely so that it withstands repeated high-current lamp discharges. Third, the rows marked "device", which give the typical operating range of the Q-switched ND-YAG devices this board feeds. A model-specific user manual and test report for ND-YAG / Q-SWITCH POWER have not been published yet; the guaranteed operating point is defined per project once the lamp, capacitor and device architecture are verified.

Frequently asked
What buyers ask before integration
Is the Q-switch driver on the board?
No. The Q-switch driver is a separate unit; this board synchronises its timing. The board itself carries the high-voltage charging circuit, the simmer circuit and lamp triggering together — so you do not need two separate boards for energy and triggering.
What happens to the capacitor energy when the device is switched off?
The board performs a controlled discharge at shutdown and during service, so the energy is released safely. Interlock, service waiting time, earthing and high-voltage isolation are verified at device level. On a board working at high voltage this is the most critical safety topic.
Does simmer require a separate board?
No. The simmer circuit sits on the same board. Because the lamp is held conductive at low current, triggering at the moment of the pulse is stable and repeatable, which protects both shot-to-shot consistency and lamp life.
What is the pulse energy?
The pulse capacitor is a 100 µF ±5% / 1400 V DC film type; at 1400 V the theoretical upper limit is 98 J. The actual charging voltage stays below the capacitor class and is set per project. Lamp type, operating voltage and target pulse energy are reviewed together.
