SVP 915 A Adjustable Voltage Protector

The SVP 915A Adjustable Voltage Protector is another model by Sinometer, designed to protect electrical appliances from voltage fluctuations, spikes, and surges. Below are its key specifications:

Input and Output

• Input Voltage: 220V AC ± 10%
• Rated Frequency: 50/60Hz

Voltage Protection

• Over Voltage Protection: Adjustable from 230V to 300V AC
• Under Voltage Protection: Adjustable from 140V to 210V AC
• Trip Delay Time: Adjustable from 0.5 seconds to 10 seconds (prevents false tripping from brief fluctuations)
• Auto Reset Time: Adjustable from 0.5 to 10 minutes (after voltage stabilizes)

Output Capacity

• Maximum Load Current: 63A
• Power Rating: Suitable for protecting loads up to 8800W at 220V

Features

• Digital Display: Shows real-time voltage readings.
• LED Indicators: For power, over-voltage, and under-voltage states.
• Hysteresis Control: Minimizes unnecessary tripping caused by minor voltage variations.
• Automatic Reset: Reconnects the load when voltage returns to a safe range.

Environmental & Design Specifications

• Operating Temperature: -10°C to 50°C
• Humidity Range: 10% to 90% RH (non-condensing)
• Enclosure: Plastic, designed for wall mounting or panel installation.

Application

• Suitable for protecting large household appliances like air conditioners, refrigerators, and other sensitive electronics from voltage instability.

SVP 912 Adjustable Voltage Protector

The SVP 912 Adjustable Voltage Protector by Sinometer is designed to protect electrical appliances from voltage surges, drops, or spikes by automatically disconnecting the load when the input voltage exceeds the preset thresholds. Here are the key specifications:

Input and Output

• Input Voltage: 220V AC ± 10%
• Rated Frequency: 50/60Hz

Voltage Protection

• Over Voltage Threshold: Adjustable from 220V to 280V AC
• Under Voltage Threshold: Adjustable from 140V to 200V AC
• Trip Delay Time: Adjustable from 0.5 seconds to 10 seconds (allows for momentary voltage fluctuations without tripping)
• Reset Time: Adjustable from 0.5 to 10 minutes

Output Capacity

• Max Load Current: 63A
• Load Power: Suitable for protecting devices up to 8800W at 220V

Features

• Automatic Reset: The device will reconnect the load after normal voltage is restored.
• Digital Display: Displays real-time voltage readings.
• LED Indicators: Show the power status, over-voltage, and under-voltage conditions.
• Hysteresis: Helps prevent unnecessary switching due to small voltage fluctuations.

Application

• Ideal for protecting household appliances such as refrigerators, air conditioners, washing machines, and other electronics from voltage fluctuations.

• Current: 30A
• It can be used in solar lighting systems with a timer and light sensor.
• Only suitable for off-grid PHOTOVOLTAIC solar systems.
• For 10A 12V PV systems: 120W solar panels, 12V lead-acid batteries, 21V for maximum input voltage
• For 20A 24V PV systems: 240W solar panels, 24V lead-acid batteries, 42V for maximum input voltage

Safety instructions

• Before installing the battery for the first time, ensure that the battery has enough voltage to enable the controller to identify the battery type.
• Battery cables should be as short as possible to minimize loss.
• The regulator is only suitable for lead acid batteries: OPEN, AGM, GEL
• It does not work with nickel-metal hydride, lithium-ion, or other batteries.
• Charge regulators are only suitable for regulating solar modules. Do not connect other charging sources to the charging regulator.

System connection

• Connect the battery to the charging regulator – positive and negative. If a 12V battery is detected, it will display 1; If a 24V battery is seen,
• Connect the PV module to the regulator – positive and negative.
• Connect the user to the charging regulator – positive and negative.
• The reverse order applies, unloading.
• The improper sequence will damage the controller!
