Ambient temperature and humidity: +5~+35℃/<80%RH Irregularity: <±15% (base level) Temperature fluctuation: <±1.0℃ Temperature deviation: <±2℃ (no load) Condensing method: water cooling/air cooling Standard: Viewing window, sample holder, UV probe, temperature probe, internal lighting, USB interface, lead test hole (with silicone plug) Optional configuration: external socket (220V 10A), electronic load, automatic scanning system, LAN interface and remote control program According to the standard: The design and manufacturing of the product have referred to the relevant industry test standards, in line with IEC61215 (design identification and type and type approval of photovoltaic modules) test standards. Irradiation area: customized according to customer test requirements (specimen size, number of single test). Irradiation intensity range: 500~1000W/㎡ Spectral range: 280-400nm(including UVA+UVB spectral band, no UVc), where UVB/(UVA+UVB) *100% is in the range of 3-10%. Drive power supply configuration: one-to-one configuration, a set of light source corresponding to an EPS electronic ballast, light stress section 50 "100%. Operation mode: fixed value programmable mode Control mode: Chinese color touch screen control; It can provide RS232, RS485, Ethernet communication interface to realize the control of the upper computer. Recording function: The touch screen displays ambient temperature, component temperature, UVA measurement value, UVB measurement value, cumulative running time, UVA irradiation dose, UVB irradiation dose, UVA+UVB irradiation dose, the controller's memory can automatically record the test curve and data, alarm status, data and curves can be downloaded via USB and exported by Excel (within one year). Auxiliary functions: fault alarm, processing prompt function; Power failure protection function; Temperature upper and lower limit warning and upper and lower limit overtemperature stop protection function; Timing automatic stop function; Power-on self-test function; There are password protected controller Settings parameters.
