The Sinotimer SVP-916 is a single-phase, self-resetting intelligent protector designed to safeguard electrical equipment from over-voltage, under-voltage, and over-current conditions. It is commonly used in residential distribution lines and household box entries. Technical Specifications
According to the SVP-916 Instruction Manual and Sinotimer manufacturer data, the device operates under the following parameters: Rated Voltage: 230V AC, 50/60Hz. Rated Current Options: 40A, 63A, or 80A (model dependent). Power Consumption: ≤ 2W. Mechanical Life: ≥ 4,000 operations. Installation: 35mm standard DIN rail mount.
Dual LED Display: The upper display shows real-time Voltage (V) and the lower display shows real-time Current (A). Parameter Settings Guide
To enter the setting mode, press and hold the "SET" button for 3 seconds. Use the ▲ (Up) and ▼ (Down) keys to adjust values. Press "SET" repeatedly to cycle through the menu until "END" appears, then press "SET" one last time to save. Adjustment Range Default Value Over-voltage Protection P01 221V–300V–OFF Over-voltage Recovery P02 220V–299V Over-voltage Action Time P03 0.1s–10s Under-voltage Protection P04 150V–219V–OFF Under-voltage Recovery P05 151V–220V Under-voltage Action Time P06 0.1s–10s (Suggest ≤ 0.3s) Over-current Protection P07 1A–40A/63A/80A Max (Model dependent) Over-current Action Time P08 0.1s–512s Fault Recovery Delay P09 Power-on Delay Time P10 Reset Mode (AU/HA) P11 Auto (AU) / Manual (HA)
Note: If under-voltage action time (P06) is set longer than 0.3s, the internal relay may not function correctly during a total power failure. Indicator Status Meanings
The LED indicators provide immediate visual feedback on the state of your power line: Voltage Indicator: Always On: Normal voltage. Fast Flashing: Over-voltage condition detected. Slow Flashing: Under-voltage condition detected. Current Indicator: Always On: Normal current load. Flashing: Over-current condition detected. Advanced Functions
Fault Inquiry: Navigate to P12 to view the last 5 fault codes. UH: Over-voltage fault. UL: Under-voltage fault. IH: Over-current fault.
Factory Reset: Simultaneously press and hold ▲ and ▼ for 3 seconds. The lower LED will turn off for 1 second to confirm the reset.
Sinotimer SVP-916 is a critical piece of modern electrical infrastructure, functioning as an intelligent over-voltage, under-voltage, and over-current protector . By analyzing the SVP-916 Manual
, we can see that this device serves as a digital "gatekeeper" for single-phase AC 230V systems, designed to instantaneously cut off power when electrical parameters deviate from safe thresholds. m.media-amazon.com Core Functionality and Hardware Design
is characterized by its "double LED digital" display, which provides real-time feedback on current voltage and load conditions m.media-amazon.com Protection Range
: It is primarily built for residential or distribution lines handling loads of 63A or less (with some variants supporting up to 80A). Response Time
: The manual highlights its ability to "cut off the power supply instantaneously," a vital feature for protecting sensitive household electronics from sudden surges or brownouts. Automatic Recovery
: A standout feature noted in the documentation is the device's ability to automatically restore power once the circuit returns to normal, eliminating the need for manual intervention after a temporary fault. m.media-amazon.com Technical Specifications and Adjustability Unlike basic surge protectors, the is highly configurable, as detailed in various Sinotimer technical guides
. The manual outlines several adjustable parameters that allow users to tailor the protection to their specific grid conditions: Voltage Thresholds
: Users can set specific upper limits (over-voltage) and lower limits (under-voltage). Current Limits
: The over-current protection ensures that the load does not exceed the rated capacity, preventing heat buildup and potential fire hazards. Time Delays SVP-916 Manual
mentions a delay mechanism, typically 1 to 500 seconds, which prevents the device from toggling rapidly during unstable "flickering" power events. m.media-amazon.com User Interface and Programming
The programming interface is designed for simplicity, utilizing a "SET" button along with "UP" and "DOWN" arrow keys. m.media-amazon.com Modification Mode
: Pressing "SET" enters the adjustment state. The manual warns that if no action is taken within 10 seconds, the device exits modification mode without saving changes. Factory Reset
: For users who may have misconfigured the device, a 3-second simultaneous press of both arrow keys triggers a factory reset, indicated by a 1-second LED flash. Visual Indicators
: The LED indicators only flash during exception events (over-voltage or over-current), serving as a quick visual diagnostic tool for homeowners. m.media-amazon.com Installation and Safety
The manual emphasizes correct wiring, usually following a standard "N" (Neutral) and "L" (Line) input and output pattern. Because it is designed for "household box entry," it is often DIN-rail mounted alongside standard circuit breakers. The device itself is built for durability, featuring low power loss and a design that ensures the protector is not damaged even when fault voltages reach their peak. Conclusion
The Sinotimer SVP-916 manual describes more than just a relay; it depicts a comprehensive monitoring solution for the modern home. By combining real-time digital monitoring with adjustable protection thresholds and automatic recovery, the SVP-916 bridges the gap between traditional fuses and sophisticated industrial power management systems. It remains a popular choice on platforms like AliExpress
