FAQ
Q1: What is the main difference between a power relay vs control relay?
A1: A control relay typically handles lower current signals (e.g., 5-10A) to interface between sensors/logic and other devices. A power relay, like the JMX-94F, is designed to switch much higher currents (80A+) and powers loads directly, often featuring more robust contacts and construction.
Q2: Can this relay be used to directly switch an AC mains load (220VAC)?
A2: Yes. The relay's contact rating is 220V, which applies to both AC and DC within its specified limits. Ensure the AC current does not exceed the 80A rating, and consider the inductive nature of AC loads for proper protection.
Q3: Is a flyback diode required for the coil?
A3: Highly recommended. When the coil is de-energized, it generates a high-voltage reverse spike. A diode placed in reverse bias across the coil terminals suppresses this spike, protecting the driving transistor or IC, a crucial step in any electrician u relays best practices.
Q4: How does this compare to a Solid State Relay (SSR)?
A4: This is an electromechanical relay (EMR). EMRs offer lower on-resistance, bidirectional current flow, and higher surge tolerance but have moving parts and a finite mechanical life. SSRs are silent, have infinite cycle life, but generate heat and may have higher on-resistance. Choice depends on application priorities like switching speed, lifetime, and load type.
Q5: Is this suitable for a new energy vehicle application?
A5: Potentially, for auxiliary systems. Its high current rating and sealed construction make it a candidate. However, automotive applications require specific qualifications (like AEC-Q). Please contact us to discuss your specific "new relay for car" requirements and potential custom solutions.
