Toroidal Transformer
Toroidal transformers are a type of transformers that is easily identifiable due to their donut like shape. The primary and secondary coils are wound around the toroidal core.
When a current flows through the primary, it produces an electromotive force (EMF) that generates a current in the secondary coil. This transfers power from the primary coil to the secondary coil.
Toroidal transformers are used in applications such as:
- Audio equipment
- Medical bed
- Inverter

EI Transformer
EI Transformer is a traditional transformer with simple structure. Its features such as iron core, frame support, support bracket, etc. are produced in large quantities. This ensures a low cost.
EI transformers are used in applications such as:
- Audio equipment
- Toys
- Lighting

Inductor for EV charger and inverter
Demand for electric cars and inverters are on the increasing. To function optimally, their charging circuits require special inductors and transformers with unique characteristics. Keen Ocean has its own production lines for this kind of special winding, assembly, potting and testing.
Inductors are used in applications such as:
- EV charger
- Inverter

Inductor
Inductors are passive electronic components used to smooth out ripple voltages so they carry direct current in electronically powered equipment.
Inductors are used in applications such as:
- Tuning circuits
- Sensors

PCB Assembly
PCB (Printed Circuit Board) Assembly is a product that combines the PCB, components and electronic accessories.
PCB Assembly are used in applications such as:
- Computer

Switching Mode Power Supplies
Switch mode power supplies use the principle of quantized power transfer to implement voltage regulation. By controlling the transistor as a switch (on or off) and energy storage elements, inductors and capacitors, switch mode power supplies transfers enough energy from input to output to attain the demand output voltage and current.
SMPS are used in applications such as:
- Computer
- Audio Equipment
- Inverter

Power Amplifier
The output power of audio amplifiers ranges from 1 watt to hundreds of watts. The radio frequency amplifier used in the system may need to generate thousands of kilowatts of output power, and the DC amplifier used in the electronic control system may also require high power output to drive many different types of actuator motors.
Power Amplifier are used in applications such as:
- Home Audio
- Cinema Audio
- School Audio
