Product descriptions from the supplier
Solid state relay (SSR) is a contactless switching device implemented using microelectronics and power electronics technology. It abandons the mechanical contacts of traditional electromagnetic relays and uses semiconductor devices to complete on-off control. The VSC series single-phase solid-state relay is a high-performance product based on this technology, which is worth considering in situations where reliable, efficient, and long-life switch control is required
dvantages of VSC series single-phase solid-state relay products:
The VSC series single-phase solid-state relays integrate the core advantages of modern solid-state switching technology: long lifespan (no contact wear), high reliability (no sparks, vibration resistance), silent operation (no action noise), fast response (microsecond level switching speed), and excellent anti-interference ability. Its compact design facilitates installation and integration, and is well compatible with common logic level signals such as TTL, DTL, HTL, requiring only a small control signal to drive high current loads.
VSC series single-phase solid-state relay product features:
1. Wide range current and voltage adaptation:
We offer three rated current specifications of 10A, 15A, and 25A, with a working voltage range of 24-280VAC, to meet the power requirements of various single-phase loads.
2. Flexible conduction mode:
Supports two output modes: Zero Crossing or Random Turn On. Zero voltage conduction effectively reduces surge current and protects sensitive loads (such as incandescent lamps and heaters); The instantaneous derivative principle is applicable to control scenarios that require rapid response.
3. Convenient installation and connection:
The design emphasizes user friendliness, with clear and intuitive wiring terminals, a simple and efficient installation process, and effectively shortens project time
4. Clear status indication:
Built in LED input status indicator light, visually displaying the on/off status of control signals, facilitating on-site installation, debugging, and operation status monitoring.
5. Inherent advantages of solid-state technology:
No mechanical contacts, completely eliminating arcs, sparks, and mechanical wear; The switch action is quiet and silent, with strong resistance to electromagnetic interference (EMI) and shock and vibration, suitable for harsh industrial environments.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
