Jumbo Digital Clocks — Choose Your Size & Synchronization Method

Electromed's Jumbo Digital Clocks are high-visibility seven-segment LED clocks available in digit heights from 2" to 12", designed for clear, accurate timekeeping across industrial, commercial, and public installations. Select the display size that matches your viewing distance requirement, then choose the synchronization method that fits your infrastructure — manual setting, GPS satellite, NTP over Ethernet, or NTP over WiFi.

Every clock in the CL series shares the same rugged MS powder-coated enclosure, high-efficiency LED display, and 220V 50Hz single-phase power supply. The manual variant requires no additional infrastructure — simply connect and set the time. Sync variants are factory-fitted with the appropriate receiver or network module for automatic, drift-free operation across your site.

Selecting the right display technology is as important as selecting the right size. For indoor installations — factories, offices, hospitals, corridors — the standard FnD (Fine Dot) LED display provides excellent brightness and clarity at normal indoor ambient light levels. For outdoor installations where the clock will be in direct sunlight, specify the DoT LED display variant, which uses a higher-brightness module designed to remain readable in full sun. For very large outdoor spaces where the viewing distance exceeds 200 metres — open yards, large campuses, railway goods sheds — specify the P10 Matrix display, which uses a dot-matrix module optimised for long-distance readability.
