Description

The TPB-UL935 Thermally Protected Ballast Heating Test Chamber is a high-temperature environment simulation device designed by LISUN specifically for electronic and electrical components such as lamp ballasts. The function is to accurately replicate natural high-temperature scenarios, verifying the thermal protection performance and high-temperature adaptability of ballasts and other components through a stable, controllable temperature environment. The equipment utilizes high-grade stainless steel inner and outer chambers and ultra-fine glass wool insulation, along with multiple dedicated strip heaters, enabling wide temperature control from room temperature + 10°C to 100°C.

The TPB-UL935 Thermally Protected Ballast Heating Test Chamber also features three switchable temperature measurement points for real-time monitoring of temperature changes at different locations during testing. It is widely used for pre-shipment thermal protection verification of ballasts, high-temperature performance optimization during the R&D phase, and high-temperature environmental testing for compliance certification. It effectively ensures the safe operation of ballasts in high-temperature conditions and avoids safety risks such as fires caused by thermal protection failure.

Specifications:

Parameters	Specifications
Internal size (LWH)	610mm610mm610mm (suitable for most specifications of ballasts, meeting batch or single sample testing needs)
Temperature range	RT+10℃~+100℃ (RT is room temperature, covering the typical temperature range of ballast high temperature adaptability test)
Temperature uniformity	≤±2℃
Temperature fluctuation	≤±0.5℃
Inner and outer box material	High-grade stainless steel plate (corrosion-resistant and high-temperature-resistant, to prevent aging or rust of the box from affecting the test accuracy)
Insulation material	Ultra-fine glass wool insulation material (excellent thermal insulation performance, reduces heat exchange between inside and outside the box, and reduces energy consumption)
Sample rack configuration	Special wooden test sample rack (good insulation, avoids heat conduction interference from metal racks, and is suitable for placing ballasts of different sizes)
Heater type	Special strip heater (size 300mm*40mm, power 300W per group)
Number of heaters and connection method	There are 4 groups in total, with power supply connected in parallel (the temperature rises quickly, a single group failure does not affect the overall test, improving equipment reliability)
Temperature measurement point	Three temperature measurement points (can be switched at any time to meet the temperature monitoring needs of different locations, such as sample surface and box environment)
Temperature control method	Intelligent PID temperature control system (automatically adjusts heating power, accurately maintains set temperature, and supports temperature curve recording)
Safety protection	Over-temperature protection (automatically cuts off heating power when the temperature exceeds the set upper limit), overload protection (avoids safety problems caused by heater failure)
Observation and operation	Equipped with high temperature resistant glass observation window (for real-time observation of sample status) and touch operation panel (for convenient temperature setting and data reading)
Power supply	AC 230V±10%, 50/60Hz, total power ≤1200W
