The power board of slimming and muscle-building devices built on EMS and HIFEM technology. It drives two coils independently, runs the pulse program and monitors coil temperature.

Product capability
Power electronics engineered for system integration.
Two coils, controlled independently.
In EMS and HIFEM devices the muscle contraction comes from magnetic field pulses produced by a coil. EMS POWER generates those pulses, runs the two channels separately and reports coil temperature back to the device controller. The board is open-frame and mounts inside your own enclosure.

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 (L / N / E)The board is supplied from 220 V AC. The protective earth (E) connection is mandatory for safe operation; as the board is open-frame, earth continuity runs through the device chassis and is verified at device level.
- Control interfaceLink to the device controller. Pulse program, channel selection and treatment intensity are sent over this line; coil temperature, ready and fault states are read back through the same interface.
- Capacitor connectionWhere the 80 µF / 2000 V DC film capacitor supplied with the board connects; charging runs over this line. Being film type, it is non-polar and has no plus-minus orientation.
- Applicator outputThe switched output the coil head connects to. Pulse current is delivered through these terminals; the second channel is wired the same way.

The values in this table come from three sources. First, the ratings of the components actually used on the board: the pulse capacitor, the bleeder resistors, the input stage and the connection hardware. Second, quantities calculated from those ratings: the energy an 80 µF capacitor holds at 2000 V, and the pulse width and peak current that follow from a resonant discharge into the coil. Pulse width and peak current depend on the coil as much as on the board, so they are given for a common inductance range — with a 114 µH coil the pulse lands close to the 300 µs figure familiar from HIFEM applications. Third, the rows marked "device" describe how the EMS / HIFEM devices this board feeds actually run. A model-specific user manual and test report for EMS POWER have not been published yet; the guaranteed operating point is defined per project once the coil, capacitor and device architecture are verified.
Integration
Planned around your device architecture.
01
Coil characterisation
Coil inductance, resistance, target field and duty cycle are evaluated technically.
02
Thermal architecture
Coil sensors, air or liquid cooling and safe shutdown thresholds are planned with the device.
03
Control program
Channel sequence, pulse program, session behaviour and user-interface commands are adapted to the OEM software.

What ships with it
One pulse capacitor is supplied with the board.
The pulse energy that drives the coil is stored in this capacitor. It is a high-voltage film type rather than an electrolytic one, selected for pulsed operation and built to ELECTROCOD specification.

The label is printed in the ELECTROCOD name; the capacitor is sourced to values we define. If the coil inductance or the target pulse energy changes, the capacitance is re-specified per project.

Frequently asked
What buyers ask before integration
Which coils does the board work with?
The coil defines the board's operating point. Across a 60-150 µH inductance range the pulse lasts roughly 220-350 µs with a peak current of roughly 1.5-2.3 kA. At the start of a project we review coil inductance, resistance, target field strength and duty cycle together.
Are the two channels really independent?
Yes. The board drives two coils independently, and the channel sequence and pulse programme are adapted to your OEM firmware. That lets you run two applicators simultaneously or alternately.
Is coil temperature monitored?
Yes. Coil temperature feedback is reported to the device controller. Sensor placement, the air or liquid cooling arrangement and safe-stop thresholds are planned together with the device. The board's own heatsink is fan cooled and provides two fan outputs.
How is pulse intensity set?
Intensity is set through the charging voltage of the pulse capacitor. Because energy rises with the square of the voltage, a small voltage change makes a clear difference in intensity. The capacitor is an 80 µF / 2000 V film type; at 2000 V the theoretical upper limit is 160 J.
