Hangtai is dedicated to high-power programmable DC regulated power supplies based on high-frequency soft-switching technology. After more than a decade of research and accumulated experience, we were the first to commercialize DC power supplies with ZVZCS soft-switching technology across the full load range, offering extremely high reliability that has earned the trust and recognition of our customers. Our programmable DC regulated power supplies have the following outstanding advantages:

1. Excellent performance and ease of use. These DC power supplies utilize peak current control and wide-bandwidth, high-gain, low-noise OPAMP, ensuring fast dynamic response and high output voltage regulation accuracy under rapidly changing loads. Additionally, the output is equipped with multi-stage filters, meeting EMI/EMC standards EN61000-6-3 and EN61000-6-1, with low output ripple.

2. High reliability—worry-free. Key components use imported parts, including original Infineon IGBT modules from Siemens Germany and control chips from UNITRODE in the U.S. Mature soft-switching technology and comprehensive protection circuits (short-circuit protection, current limiting protection, over-temperature protection, over-voltage protection, over-current protection) ensure reliable IGBT operation.

3. High efficiency—cost-saving
ZVZCS soft-switching technology enables high efficiency, low noise, and high reliability; overall efficiency exceeds 85%. In contrast, high-power DC regulated power supplies from other domestic manufacturers mostly rely on hard-switching and thyristor phase-controlled rectification, resulting in low efficiency and poor reliability. Using our DC power supplies can save users significant electricity costs annually.

4. High power density—space-saving. Thanks to the adopted soft-switching conversion technology, our products offer high quality, compact size, light weight, high power density, and space efficiency.

5. High switching efficiency—quiet operation. With switching frequencies above 24kHz, beyond the range of human hearing, there is no annoying audible noise. Combined with noise suppression technology, it creates a quiet and comfortable working environment.
