Power Supply Options
High–low temperature chambers are supplied by default with a three-phase 380 Vac power input, which is standard for industrial laboratory environments in many regions.
For customers operating under different electrical standards, alternative power configurations are available upon request, including three-phase 208 Vac input, commonly used in the United States, Canada, and other regions.
Power supply customization is supported during the project configuration stage to ensure compatibility with local electrical infrastructure and safe, stable long-term operation.
Integrated Channel Capacity Overview
For all-in-one chamber systems, the number of battery testing channels that can be integrated depends on both the available installation space inside the chamber (e.g., 5U, 6U, 9U, 12U, 32U) and the current range of the test channels (e.g., 100 mA, 6 A, 15 A, 30 A, 75 A, 300 A).
Higher current channels require larger power modules and thermal clearance, which directly affects how many channels can be accommodated within a given space. The chart below provides a clear reference indicating the typical channel capacity for each chamber model, based on internal space allocation and selected current ranges.
Final configurations can be adjusted during project definition to balance channel density, current capability, and long-term operational stability according to specific test requirements.

General Safety and Maintenance Requirements
Environmental test chambers shall be operated and maintained in accordance with the instructions specified in the user manual. Correct operation and regular maintenance are mandatory to ensure safe use, measurement reliability, and long-term equipment integrity.
1. General Safety Instructions
- The equipment shall only be operated by trained personnel.
- Before commissioning, relocation, or re-commissioning, the equipment shall be inspected for correct installation and electrical grounding.
- The chamber shall be connected to a power supply that conforms to the specified electrical ratings.
- The use of knife switches, non-rated sockets, or unreliable grounding connections is prohibited.
2. Requirements Before Operation
- The user manual supplied with the equipment shall be read and understood prior to operation.
- After relocation of the equipment, the chamber shall be re-leveled before use.
- For chambers equipped with humidity control, the water tank level and water supply condition shall be checked before operation.
- Test samples that may be displaced by airflow shall be properly secured using suitable fixtures or protective mesh.
3. Requirements During Operation
- The chamber door shall not be opened while the refrigeration system is in operation, in order to prevent compressor damage caused by liquid return or frosting.
- After power-on, a minimum preheating period shall be observed before initiating cooling or temperature cycling, to ensure proper compressor lubrication.
- Excessive start–stop cycles of the compressor shall be avoided. Frequent starts may significantly shorten the service life of the compressor.
- For chambers with humidity control, water pipelines shall be inspected regularly for blockage, leakage, or damage.
4. Requirements After Operation
- After high-temperature testing (≥80 °C), the chamber temperature shall be reduced to ambient temperature before shutdown, in order to prevent damage to test samples, equipment components, and potential injury to personnel.
- After low-temperature testing (≤0 °C), the chamber temperature shall be raised to approximately 60 °C for a short period prior to shutdown, to prevent condensation, frosting, or fan blockage.
- Test samples shall be removed promptly after testing.
5. Routine Maintenance
- The inner chamber shall be cleaned on a regular basis to maintain a stable and contamination-free test environment.
- Condenser fins shall be cleaned periodically to ensure effective heat dissipation.
- For water-cooled or humidity-controlled chambers, water filters shall be cleaned and residual water shall be removed from the circulation system as required.
- Consumable components (e.g. wet-bulb gauze for humidity systems) shall be replaced when discoloration, contamination, or degradation is observed.
Important: Failure to comply with the above requirements may result in reduced equipment performance, shortened service life, or safety hazards. Detailed maintenance procedures and intervals are specified in the official user manual supplied with the equipment.
