Name: TB388 Mechanical Time Switch
Brand: MY SHOP

Description

Product Overview

TB388 is a quartz driven timing switch designed specifically for harsh industrial environments. It features a clock style dial and a fully embedded setting handle. Users can quickly calibrate the time by adjusting the knob. The minimum setting unit of 15 minutes supports up to 96 independent timing tasks, meeting the needs of refined management. The product is equipped with an industrial grade quartz motor drive system, with a monthly time accuracy error controlled within ± 15 seconds and an action time accuracy of ± 3 minutes, ensuring precise execution of timed tasks. Built in rechargeable nickel hydrogen battery, providing up to 300 hours of power outage compensation function, even in the event of prolonged power outage, the timing program will not be lost; It supports on/automatic/off three mode switching and can quickly switch between preset timing and manual control to meet emergency operation requirements. Adopting standard 35mm guide rail installation, compatible with various types of distribution box integration, and adaptable to different global power grid environments through wide voltage design (85-264VAC), the contact capacity can reach up to 15A, which can directly control various loads such as lighting, motors, heating equipment, etc. It has passed authoritative certifications such as CE and UL, making it an ideal choice for achieving high reliability automated timing control.

Main Features

1. Industrial grade precise timing: The quartz motor drive ensures a monthly time accuracy of ± 15 seconds, an action time accuracy of ± 3 minutes, a minimum setting unit of 15 minutes, and can set up to 96 independent timing tasks to meet the needs of refined management.
2. Ultra long power outage compensation: Equipped with a rechargeable nickel hydrogen battery, it provides 300 hours of power outage compensation function. Even in the event of a long power outage, the scheduled program will not be lost, ensuring task continuity.
3. Flexible switching of three modes: It supports switching of three modes, namely, on/automatic/off, and can quickly switch between preset timing and manual control, to meet emergency operation requirements and improve the flexibility of use.
4. Global Grid Adaptation: Designed with a wide voltage range of 85-264VAC, compatible with 50/60Hz power frequencies, and adaptable to different global grid environments, it can be used directly without the need for additional transformers.
5. High load multi scenario compatibility: The contact capacity can reach up to 15A, which can directly control resistive loads (15A), incandescent lamps (15A), reactive loads (12A), and motors (1500W/220VAC), meeting different power requirements for industrial and civilian use.
6. Anti misoperation design: Clock style dial with minute adjustment knob, can quickly calibrate the current time; Fully set handle embedding method to avoid misoperation and ensure precise and error free timing settings.

Application Scenarios

1. Industrial production automation: timed control of production equipment preheating, timed defrosting, assembly line start stop, etc., optimizing production processes, improving production efficiency, and reducing energy consumption.
2. Commercial lighting and display: Automatically control the on/off time of store signs, advertising light boxes, and window display lights to increase brand exposure while reducing energy costs.
3. Commercial refrigeration and HVAC: Set timed defrosting and operating periods for commercial refrigeration equipment and air conditioning systems to balance equipment operation and energy-saving needs, and extend equipment service life.
4. Intelligence of Civil Facilities: Control the timed operation of household appliances such as water heaters, electric heaters, and ventilation fans to improve convenience in daily life and reduce energy waste.
5. Public facility management: In office buildings, schools, hospitals and other places, control the lighting, elevators, air conditioning and other equipment in public areas at regular intervals to achieve refined energy management.
6. Special environmental control: Implement timed cyclic operation in sewage treatment systems, generator testing, swimming pools, and hot spring equipment to ensure stable system operation.
