The SL Power Electronics GLC75-28G is a cost-effective, single-output AC DC power supply designed for global performance. It operates with a universal input voltage range of 90-264 Vac and delivers up to 75W of continuous output power under natural convection cooling, or 110W with forced airflow.
This open frame converter meets 1U applications with its compact dimensions of 3.4" x 5.75" x 1.56". It is approved for commercial applications to UL1950, CSA22.2 No. 234, IEC950, and EN60950 standards, and for medical applications to UL2601-1, IEC601-1, and CSA22.2 No. 601. The unit includes built-in EMI filtering to meet FCC Class B and CISPR 22 Class B conducted emissions requirements.
Key electrical specifications include an efficiency of 72-85%, output regulation within 0.5% rms, and transient response time of 500 µs. Overload, short circuit, and overvoltage protection are standard features. The power fail signal is TTL/CMOS compatible, indicating output voltage drop before AC power loss.
The normal continuous output power is 75 W for unrestricted natural convection cooling, and 110 W with 26 cfm airflow.
The unit accepts a universal input voltage range of 90-264 Vac.
The dimensions are 3.4" x 5.75" x 1.56", which is 146.0mm x 86.4mm x 39.7mm.
It is approved for commercial applications to UL1950, CSA22.2 No. 234, IEC950, and EN60950, and for medical applications to UL2601-1, IEC601-1, and CSA22.2 No. 601.
Yes, it includes built-in EMI filtering to meet FCC Class B and CISPR 22 Class B conducted emissions requirements, and complies with EN61000-3-2 Class A.
The operating temperature range is 0°C to 50°C.
It includes overload protection (power limiting), short circuit protection (cycling type power limit), and standard overvoltage protection.
