  • Q What are your prices?

    A Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contact us for further information.
  • Q Do you guarantee safe and secure delivery of products?

    A Yes, we always use high quality export packaging. We also use specialized hazard packing for dangerous goods and validated cold storage shippers for temperature sensitive items. Specialist packaging and non-standard packing requirements may incur an additional charge.
  • Q Can you OEM or ODM?

    A Yes, we have strong developing team. The products can be made according to your request.
  • Q Can you supply the relevant documentation?

    A Yes, we can provide most documentation including Certificates of Analysis / Conformance; Insurance; Origin, and other export documents where required.
  • Q What is the average lead time?

    A For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. The lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. If our lead times do not work with your deadline, please go over your requirements with your sale. In all cases we will try to accommodate your needs. In most cases we are able to do so.
  • Q What kinds of payment methods do you accept?

    A You can make the payment to our bank account, Western Union or PayPal:
    30% deposit in advance, 70% balance against the copy of B/L.
  • Q What is the product warranty?

    A We warranty our materials and workmanship. Our commitment is to your satisfaction with our products. In warranty or not, it is the culture of our company to address and resolve all customer issues to everyone’s satisfaction
  • Q Do you have a minimum order quantity?

    A Yes, we require all international orders to have an ongoing minimum order quantity. If you are looking to resell but in much smaller quantities, we recommend you check out our website.
  • Q How about the shipping fees?

    A The shipping cost depends on the way you choose to get the goods. Express is normally the most quickest but also most expensive way. By seafreight is the best solution for big amounts. Exactly freight rates we can only give you if we know the details of amount, weight and way. Please contact us for further information.
  • Q Precautions

    A 1、All relays are shipped in the “closed”position.It is possible that during transit or final assembly the relay could change its state to the “open”position.
    Therefore,it is recommended that all relays be set to the desired state of the relay via a power supply.
    2、In order to maintain an “open” or “closed” state of the relay,the coil voltage should reach the rated voltage. The pulse width should be 5 times the operating time to ensure a proper change of state.Do not energize both T1 and T2 at the same time on a dual coil or energize the coil for longer than 1 minute (damage to the coil could incur).
    3、Relays have polarity,if the user’s need different from information,shoud be contact us.
    4、The relay to the factory inspection and use should handle to prevent damage effect,to the factory for damaging the goods shoud be strict distinction between the normal product and must not uses.
  • Q About contact load


    All con tact current marked on Relay and the catalogue are resistive load, if not specified.
    Under rated switching voltage, the inductanee load should not exceed 30%, motor load should not exceed 20%, light load should not exceed 10%, capacitive load should not exceed 5% of rated resistive load.
    We recommend to choose contact load current not exceeding 60-70% of the steady state current in view of reliability.
    Please refer to below table for in-rush current at different loads:

    Load type Resistive Sodium lamp Mercury lamp Inductive Motor Transformer Incandescent Capacitive
    In-rush 1 time 1-3 times 3 times 3-5 5-10 5-15 times 5-15 times 20-40
    current times times times
