The FH15D offers multiple rated coil voltages, including DC 5V, 6V, 9V, 12V, 18V, and 24V.
This relay is highly suitable for the following equipment and systems:
Photovoltaic inverters, Energy Storage Systems (ESS)
Electric vehicle charging equipment
Industrial automation control systems, PLC modules
Communication base station power supplies, Power Distribution Units (PDUs)
Medical equipment, Test and measurement instruments
PCB Configuration and Separation: The product incorporates magnetic components. To avert reciprocal interference that may induce parameter alterations or soldering complications, ensure a minimum separation of ≥20mm for adjacent installations and ≥25mm for staggered configurations.
A varistor should be installed in parallel across the coil terminals to mitigate the surges that are induced.Select a varistor with a voltage rating that is approximately three times the rated voltage of the coil.
Environmental Precautions: It is recommended to refrain from operating in areas with strong magnetic fields, as this may impede the ability to extinction arcs and impact the engagement/release parameters.
Polarity Note: Contact terminals are non-polar, but coil terminals require polarity.If the coil voltage is sustained or diminished during operation, the positive terminal must be linked to the specified pin.
Management Safety Measures: Exercise caution and refrain from dropping the product to maintain its original performance specifications.
The FH15D relay stands out as a star product for high-voltage DC control applications, combining miniature size, robust power handling, and high reliability. It meets your high standards, whether you care most about safety, a longer lifespan, or being able to adapt to different environments.
