ACMAS Technologies Pvt. Ltd.
Weiber Altitude Test Chamber combine temperature and altitude to test basic components or subassemblies designed for use in a variety of industries. With altitude test chambers, user can control the temperature environment for testing while simulating various altitudes from site level to 10,400 meters (25kPa). Altitude testing may be continued without temperature control up to 600,000 meters (0.1 kPa).High Low Temperature Altitude Test Chamber is used to test temperature and low-pressure altitude conditions simultaneously. Two common applications of High Low Humidity Altitude Test Chamber are testing of avionics or other aerospace equipment to simulate actual conditions, and simulate high-altitude conditions found in mountainous regions or other regions. All models are factory tested, with an ergonomic and maintenance cum user-friendly design. These CE approved test chambers are created with multi-layered insulation with double vapour barrier is of low 'K' factor, high density and of non-hygroscopic in nature. Weiber test chamber are made in accordance with the international standard. Weiber Test Chambers are GMP complaints and are also ISO and NABL certified.

Zhejiang Sandi Electric Co., Ltd
SANDI SDT series single-phase to three-phase converter, adopted SVPWM modulation control technology, which can convert ordinary single-phase power to industrial three-phase power. After through SDT series single-phase to three phase converter power conversion, the three-phase power output is standard pure sine wave, the harmonic distortion rate (THD) is less than 2%, totally meet the national standards of three-phase power quality, applicable to all types of load.The SDT series single-phase to three-phase converter can solve production inconvenience because of some areas with the three-phase electric power restrictions, also solved some user requirements that can?謒?apply for the three-phase electric because of space limitation.Features1) Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It's service life can up to 15 years or more.2) Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the type of their load. This function is very convenient for users and also reduce frequency converter?謒?usage, which reduced the cost of equipment investment, easy to connect wires and control.3) Pure sine wave output with good transient response less than 50ms, waveform distortion is very little, higher conversion efficiency and stable output voltage.4) Adopted low frequency transformer which ensure the input voltage and output voltage are completely electrical isolated to avoid interference.5) Using SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses conversion efficiency up to 94%.6) Output AC Power is suitable for all types of electric appliances, electric tools, electric motors etc. higher capability of driving load.7) Converter has the function of filtering the grid disturbance and interference at the same time, which is a good performance of stabilized voltage and frequency power, to provide a more stable and pure power supply environment for the backend devices.8) Output perfect protection function, with output over-voltage, overload, short circuit, over temperature, self-diagnosis protection and other protection.9) High conversion efficiency, high instantaneous power and low load loss.10) The input voltage, output voltage, frequency and phase can be custom made.SpecificationModel SDT-40KWIsolation mode Low Frequency TransformerAC InputRated voltage (Vac) 240V single-phase 60HZVoltage range (Vac) 190-270VInput current (A) 167AAC OutputRated power (KW) 40KWRated voltage 240V ± 2%Output phases Three-phase with Neutral wires (L1, L2, L3 + N)Rated current (A) 96AOutput frequency 60Hz ±0.05 (50HZ can be set)Waveform Pure sine waveVoltage accuracy Load balancing≤1%、Unbalanced load≤5%Waveform distortion rate (THD) Linear load≤2%、Nonlinear load≤3%Dynamic Response 5%，≤50ms (load 0～100%)Power Factor (PF) 0.99Inverter Efficiency ≧85%Electrical insulation properties 2000Vac、1 MinuteProtection FunctionOverload Ability 150%、10sProtection Input under voltage, overvoltage, output over-current, short circuit, overheating etc.Display LCD+LEDMethod of working Working continuouslyCooling method Intelligent fan coolingShort-circuit protection No automatic recovery, need to restart the machineWorking Environment & Mechanical dimensionDegree of protection IP20 (indoor)Working Altitude（m） ≤3000mWorking temperature (℃) -20～+50℃Relative humidity (℃) -25～+85℃Noise (1 meter) ≤60dBReference size: (W x D x H) 750×750×1480mmReference net weight (Kg) 340Kg
