Variable load resistor is actually the assembly of load and resistance. Load, as the name implies, refers to the electronic components connected at both ends of the power supply in the circuit. The main function is to convert electric energy into other forms of energy to achieve energy conversion. Load resistance is a kind of resistance, which refers to the "load" in the circuit, that is, the resistance of the working equipment in the circuit. For example, the resistance of a bulb in a lighting circuit is the load resistance.
Feature
This type of resistor has large power, and is generally a non inductive power resistor. Non inductive value and ultra-low inductive value are important requirements for such products. In the process of absorbing power to discharge excess electricity, if the inductance value of the variable load resistor is too large, it is easy to produce vibration, which will damage other components in the circuit, power supply and equipment itself, or even directly burn out many internal components.
Resistors are often used as loads to absorb unnecessary power generated during product use, or to buffer and brake. In addition, for high-precision resistors, it is not allowed to have high impedance in the product, which requires the selection of high-quality materials and highly demanding processes.
Application area
Large power supply equipment, medical equipment, electrical equipment and other products often need to absorb some of the excess power generated in use. The resistance of high power consumption used here is the load resistance. Load resistance is also called discharge resistance, braking resistance, braking resistance and absorption resistance due to its special role.
Variable load resistor is widely used in communication, civil aviation, banking, securities, railway bureau and other industries. It is a necessary test tool for acceptance and daily maintenance of various generator projects, and a necessary test tool for acceptance and daily maintenance of UPS equipment projects.

1. Q: Are you a manufacturer or a trading company?
Yes, we are the manufacturer. Our company has 15 years of professional experience in the field of telecommunications and can design and manufacture various microwave waveguide components, coaxial components, antennas and other telecommunications components for the global market.
2. Q: How do I place an OEM order?
A: 1. We will manufacture these products according to the mechanical drawings you provide. Some minor changes may occur during the production process to ensure that we can meet your electrical specifications. Or we can take the first set as a sample to see if it meets your specifications. After communication, the buyer and seller reached an agreement on product details, packaging, purchase quantity, unit price, delivery time, payment terms, etc.
2. The buyer sends a formal PO (Purchase Order) or the seller sends a formal PI (proforma invoice) with detailed terms and conditions.
3. Q: How to solve the after-sales service problem?
After receiving the goods, if you have any dissatisfaction or other problems, please contact us as soon as possible, we will give you a quick response and reasonable solution.
4. Q: How long is your delivery time?
A: Usually 7-15 business days after receiving 100% payment. For bulk orders: 15-35 working days after receipt of deposit.
5. Q: How do I get samples?
A: We need to receive your payment before we can send the sample to you. After the customer confirms the order, we will reduce the sample cost. However, if you are a regular customer of ours, we can send you a sample and then deduct it from your account on the next transaction.
6. Q: What are your payment terms?
A: For small batch orders or urgent orders, you can choose PayPal, Western Union, escrow for the convenience of buyers, 100% payment before delivery; For large orders: 30%/50% of T/T as deposit, balance before shipment.
7. Q: What about the warranty?
A: We can provide a 1-year warranty.
