The product catalog has been updated: AC Electronic Load 63800 Series.

AC electronic load with optimal power factor and crest factor for three-phase output product applications.

The 63800 series is suitable for testing power devices such as uninterruptible power supplies (UPS), off-grid inverters, AC power sources, switches, and breakers. Even when the voltage waveform is distorted, the 63800 series can simulate load conditions with high peak factors and varying power factors while performing real-time corrections. This capability allows for real-world simulations, yielding reliable and unbiased test results. Additionally, using DSP technology, it can simulate nonlinear rectifier loads through a unique RLC operating mode. In this mode, it detects the DUT's impedance and dynamically adjusts the control bandwidth of the load to ensure system stability. The comprehensive measurement capabilities of the 63800 series allow for monitoring the output characteristics of the DUT. Furthermore, voltage and current signals can be verified on an oscilloscope via analog output. Standard interfaces such as GPIB and RS-232 are used for remote control and measurement data transfer for system integration. Additionally, the built-in digital output can be used to control external relays for short-circuit (crowbar) testing.

By utilizing the software, it is possible to conduct international standard tests IEC61000-4-11/4-13/4-14/4-28, and inrush current tests can also be performed through phase control during ON/OFF operations. This power supply can be used in a wide range of fields, from R&D testing based on various standard tests to automated testing systems on production lines.

• power supply

High-performance stabilized AC power supply with excellent cost performance.

The 61600 series is a stabilized AC power supply that combines low cost, multifunctionality, and convenience. The output voltage variable range is 0 to 350 VAC, and the frequency variable range is 15 to 2000 Hz. By adopting PWM technology, it is capable of delivering a peak current that is six times the rated current.

• Power Supplies

DC electronic load with a module + mainframe structure. Multi-channel type, high precision, high output, equipped with constant impedance mode.

The 63600 series is designed to test multi-output AC/DC power supplies, DC-DC converters, mobile phone chargers, batteries, PC adapters, and power electronics products, making it suitable for applications such as research, development, production, and acceptance testing. It features a CZ (constant impedance) mode that simulates capacitive loads and can also emulate nonlinear loads. The minimum operating voltage is (0.4V @ 80A Typical, 63640-80-80), allowing it to draw rated current even at low voltages, making it suitable for applications requiring low voltage, such as fuel cells. Additionally, it meets the testing requirements for ATX power supplies by providing extensive simulation capabilities for dynamic loading applications. The built-in EEPROM memory allows for the immediate recall of 100 sequences of stored data for testing. The 16-bit measurement circuit performs real-time voltage and current measurements, enabling voltage measurement, adjustment, and short-circuit testing to be simulated through both the front panel and software via a PC.

• Electronic Load Unit

A DC electronic load that can simulate LED electrical characteristics in a module + mainframe configuration.

The LED driver supplies the energy that serves as the light source for the LED and is designed as a constant current source for the LED. The characteristics of an LED driver differ from those of a typical switching power supply, but the structure is very similar. To evaluate an LED driver, it is possible to perform operational checks using actual LEDs, resistors, and electronic loads with CR/CV modes, but it can be challenging to meet the testing conditions. When evaluating an LED driver with a resistor, the relationship between voltage and current becomes linear, as shown by the blue line, which does not fully utilize the characteristics of the LED. When using a DC electronic load with CR/CV modes, it is desirable for both CR and CV modes to operate stably. However, during LED ON/OFF tests or dimming tests, the protection circuit of the LED driver may cause instability in the operation of the electronic load, posing a risk of not being able to conduct the tests successfully. Using actual LEDs as a load can lead to degradation issues over long-term use and requires significant labor to test various types of LED drivers. Chroma has prepared the 63110A/63113A/63115A, based on the 6310A series, to solve the testing issues for LED drivers.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
