Socket & See Voltage Indicator Proving Unit 36mA Output Voltage 50V to 690V SP 200

Socket & See SP 200 Voltage Indicator Proving Unit delivers a professional and reliable method to verify the correct operation of multimeters and two-pole voltage indicators. This unit outputs an AC voltage ranging between 50V and 690V with a test current of 36mA, generating a true test waveform that closely simulates real AC voltage conditions up to 230V at 36mA typical output. The device is powered by six AA alkaline batteries, offering approximately 10 hours of battery life with average usage.

The compact design encourages routine safety checks in industrial, electrical testing, and maintenance applications, ensuring equipment functionality and user safety. Step voltage LEDs display voltage levels at 50V, 100V, 230V, 400V, and 690V for clear indication during testing. The unit also features an automatic test function that helps conserve battery life and a low battery indicator to alert users before the battery is depleted.

Operating reliably within a temperature range from -10°C to 40°C, the SP 200 proving unit is powerful enough to light old filament-style lamps, making it useful for diverse electrical testing scenarios. It is ideal for use by electricians and technicians working with digital multimeters, clamp meters, and electrical testers to confirm voltage presence and system status before and after work, aligning with recommended Health and Safety Executive (HSE) guidelines.

Construction and manufacturing environments, laboratories, electrical maintenance teams, and safety testing professionals will find this proving unit indispensable for ensuring device accuracy and safety compliance. The product is CE marked and complies with BS EN 61010-1:2010 standards, ensuring quality and reliability for electrical test and measurement tools.

Output voltage ranges from 50V to 690V AC. Test current rated at 36mA for precise verification. Powered by six AA alkaline batteries for portability. Compact size: 130mm length, 65mm width, and 49mm height. Lightweight at 350g for easy handling.
