Brief introduction: Microprocessor based servo controlled temperature system. The microprocessor-controlled unit allows for three settings, pre-warm, manual or automatic. Alarms functions for safety includes: Power failure temperature deviation Temperature probe failure over temperature Convenient x-ray cassette under infant bed. Three variable mattress tilts. Separate white lamp allows convenient observation. Adopts anti-explosion micro crystal quartz infrared radiation tube for its radiation source . Having quick heating and long life span. Digital display to indicate temperature. Have independent the second heat cuts off , the system is more safe. Protection when temperature probe in over temperature. Technical specification: Electrical requirement : 220v+10%/50+2% Power supply : _1500va Temperature control range: 32~38.5 Temperature probe accuracy: _0.3 Mattress temperature uniformity: _2.0 Warm-up time: _45min Adjustable horizon angle of radiator: +90 Operation condition: Environment temperature: 18~30 Environment relative humidity: 30%~75%rh Environment air velocity of flow:
