Profile: Shenzhen Okerda Science & Technology Co., Ltd. specializes in manufacturing custom designed transformers, coils and power supplies. Our products include toroidal transformers, AC/DC adapter, battery charger, PCB mounting transformers, inverters, high frequency transformer, UPS, machine tool control transformer, switching power supply, encapsulated transformer, mini circuit breaker and AC contactor. Our lead-acid battery charger works on switching mode and offers high efficiency. It adapts 3-stage charging technology and inflow the optimal current. Its equalizing charge mode removes gabs of capacity between cells, caused by general charge with keeping the battery in best condition and improves battery's capacity & increases the life of battery. The surface mount inductors are available on tape and reel for automatic insertion. They have a flat top and robust temperature deflection to prevent damage during solder reflows. These are available in magnetically shielded or unshielded versions. Their high energy storage & very low resistance make them the ideal inductors for DC-DC converter and PDA. We also offer custom indicators as per requirement and specifications. These are widely used for VTR, LCD television set, satellite receivers, car audio systems, mobile phones, pagers, notebook computers, DC-DC converters, industrial machines, and portable communication systems. We also export our products to various countries worldwide.
