Model Number: ZL-7928A Style: Embedded,Max Measuring Temperature: 70 Celsius- 99 Celsius,Display Type: Digital,Usage: Industrial Power Type: Charger,Theory: thermostat, hygrostat, hatching 220/110Vac and/or 12/24Vdc power supply All outputs could be different voltages respectively,full battery system, including all outputs, to meet:power supply often loses,solar energy source system,wind energy source system,Drive any size (egg qty.) incubators Power supply: 110/220Vac, and/or 12Vdc backup Power supply consumption: 3W Outputs: different output voltage for different output Power supply: 12VDC Output for heaters: 12, 24VDC. Rated current less than or equal to 10A for every output Output for others: 12VDC. Rated current less than or equal to 5A for every output For larger size incubator, it needs bigger heating energy. For 110/220Vac heaters, the controller heat1/heat2 output drives the following component(s in parallel): The controller PIN14 supplied with 110/220Vac. The component input is 110/220Vac. The components could be used: SSR-40AA Megetic contactor Relay (eg.: JQX-38F xx0VAC) The controler PIN14 supplied with 12Vdc. The component input is 12Vdc. The componest could be used:
