TVPS1 Series Voltage Protection Ammeters Models: TVPS140A, TVPS163A, TVPS163K Mini Overview A compact DIN rail mount voltage protection ammeter designed for 230 VAC power systems. Provides adjustable overvoltage and undervoltage protection, automatic recovery, real time voltage display, and voltage correction to protect equipment and improve system reliability. Key benefits Protects connected equipment from harmful voltage excursions by disconnecting loads on overvoltage or undervoltage events and automatically restoring power when conditions to safe levels. Adjustable set points and timing let you tailor protection behavior to specific equipment and operating conditions. Built for panel and cabinet mounting on standard 35 mm DIN rail, available in a mini version for space constrained installations. Low standby power consumption and a long mechanical switching life for reliable continuous operation. Core functions Overvoltage protection with adjustable trip and recovery thresholds. Undervoltage protection with adjustable trip and recovery thresholds. Automatic recovery after voltage returns to the selected recovery threshold. Continuous voltage display and voltage correction function. Configurable action delay and recovery delay to avoid nuisance trips. Technical specifications Power supply: 230 VAC, 50/60 Hz Maximum continuous load: 40 A or 63 A depending on model Models: TVPS140A, TVPS163A, TVPS163K Mini Overvoltage protection range: adjustable 230 V to 300 V; protection can be turned off Overvoltage recovery range: adjustable 225 V to 295 V Overvoltage action time: adjustable 0.1 s to 30 s, default 0.5 s Overvoltage recovery delay: adjustable 1 s to 500 s, default 30 s Undervoltage protection range: adjustable 140 V to 210 V, default 170 V Undervoltage recovery range: adjustable 145 V to 215 V, default 190 V Undervoltage action time: adjustable 0.1 s to 30 s, default 0.5 s Undervoltage recovery delay: adjustable 1 s to 500 s, default 30 s Poweron delay: adjustable 1 s to 500 s, typical factory default 10 s Power consumption: less than 2 W Mechanical switching life: 100,000 cycles Mounting: 35 mm DIN rail Installation and operation notes Mount on a standard 35 mm DIN rail inside control panels or distribution boards. On first power up, allow the configured poweron delay time before the unit begins normal operation. Typical factory poweron delay is 10 seconds. The unit indicates readiness with the status light turning off. Configure trip thresholds and timing to match the needs of the protected equipment. Default settings provide moderate protection out of the box. Typical applications Protection of household and commercial appliances in single phase 230 VAC installations to prevent damage from sustained voltage spikes or brownouts. Integration into small to medium electrical control panels for machinery, HVAC, and lighting circuits where voltage stability is required. Protection of inverters and power supplies in renewable energy systems or backup power setups, ensuring connected loads are disconnected during unsafe voltage conditions and reconnected when stable. What makes it stand out Wide adjustable ranges for both overvoltage and undervoltage thresholds and delays allow precise tailoring to diverse systems. Compact DIN rail form factor including a mini model for tight spaces. Durable switching mechanism rated for repeated cycles and low standby power consumption. Use the TVPS1 series to add robust, configurable voltage protection with clear voltage indication and automatic recovery for a variety of 230 VAC applications.
