Featuring an OLED display, it calculates sunrise and sunset times based on your coordinates, enabling energy-efficient, sensor-free control. With 500 event capacity, dual program modes, and a robust 16A relay output, it ensures precise, reliable operation backed by a 6-year calendar memory and password security. Ideal for smart street lighting, building illumination, and industrial equipment control. ## Description Product Description Timer REV-303 is a microprocessor-based programmable device designed to control the loads in real time without permanent maintenance with minimum expenses and maximum electricity saving. Timer REV-303 can be used to switch on the heating system, pumps, fans, school signals, street illumination, highlighting of building facades (around territories, car parking and other objects). Timer REV-303 can automatically define the time of sunrise and sunset on the basis of entered coordinates (latitude & longitude) and current time which enables to control the illumination (street light) without using the external sensors. Timer REV-303 features Two programs of control with quick switching over between them (P1 & P2); Four operational modes of timer (astronomical, weekly, daily and simple modes) ; Calendar with operational life for 6 years period without external power supply; Accuracy of planned events 1 second and 0.1 second in simple mode of timer; Total internal memory for 500 independent events, divided between the programs; Automatic shift for summer time and winter time; Light-emitting graphical display (OLED); Indication of current state of relays contacts; Control of timer with 4 buttons, located on the front panel; Possibility to set an access password for setup menu; Power supply from the electric line 24 – 265 V 50/60 Hz or from DC source of 8-24 V battery; 16A relay output @ 250V AC In Astronomical mode, every day the timer calculates the real time of sunrise and sunset based on latitude & longitude of any location, sums this time with the time of event, and then the resulted time is referenced with the clock of real time and if the resulted time is more or equal to real time – the time will switch the load relay in state which is assigned by the event. Multifunctional Astronomical Timer Model: REV-303 Display: Graphical OLED display, Voltage: 24-240V AC 50/60 Hz & 8-24V DC, Output: 16A (3.5 kW) @ 250V AC SPDT (1NO+1NC). Application: Astronomical Time Switch, Daily-Weekly Timer, Lighting System Smart Control, Street Light Automation, Indoor and Outdoor Lighting Automation, Machine/Equipment (pump) On/Off operation. Events: 500 events spread over 2 selectable preset programs (P1 & P2).
