According to the difference in the number of output phases, it can be divided into single-phase and three-phase AC power supplies.
The output power of single-phase adjustable AC power supply ranges from 500VA to 200KVA, the output power of three-phase adjustable AC power supply ranges from 3KVA to 600KVA, the output voltage is divided into 0 ~ 150Vac, 150 ~ 300Vac, and the output frequency is adjustable from 45Hz to 70Hz with 50/60Hz fixed frequency output.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies.
This series of adjustable AC Power Supplies have comprehensive protection functions, such as: over voltage, over current, over temperature and short circuit protections, which can protect the AC power supplies and DUT from damages. At present, it is mainly used for Various electrical appliance manufacturers conduct grid simulation tests on electrical appliances according to the voltage/frequency requirements of different countries. Imported electrical appliances are used for the domestic demand for variable voltage and frequency conversion, as well as various AC motors and AC transformers.
Summer hotspot: ELISA kit for transportation and storage - Database & Sql Blog Articles
During the peak of summer, whether you're in the South or the North, the high temperatures can significantly impact the performance of ELISA tests. It’s crucial to ensure that ELISA kits are properly stored and transported, especially during hot weather.
Elisa kits are essential tools in many diagnostic and research settings. Their reliability depends heavily on correct storage and handling. Under normal conditions, ELISA kits should be stored at 2–8°C for up to one month. For better results, it's recommended to store them at 4°C, especially for enzyme-free kits. If long-term storage is needed, -20°C is ideal, and the test plates should be sealed in aluminum foil bags to prevent moisture exposure. This method ensures the kit remains effective for up to six months.
However, transporting these kits during summer presents a challenge due to high ambient temperatures. To maintain their integrity, several precautions should be taken:
1. Use an insulated package with built-in ice packs to keep the temperature between 2–8°C during transport.
2. Place the kit in an EPS foam box with triple-layer protection to prevent damage from shocks or crushing.
3. Store the kit and all related documents in a ziplock bag to protect against water and humidity.
4. Choose a 25mm thick foam box for added waterproofing and durability during transit.
