Description5A is rated current. The unit can work long hours at this current and good cooling environment. The actual output current depends on circuit loads. Please DO NOT let the unit work long hours over rated current! Normally it is better to work under 80% of rated current.Features- Color: Shown in the pictures. - Material: Mainly metal. - Size: Approx. 19.8 * 9.8 * 4.2cm/ 7.8 * 3.9 * 1.7 inch (LWH). - Input: AC 100-240V. - Output: DC 24V 5A. - L, N, GND: AC power input. - +V: DC power output "+". - -V: DC power output "-". - +V / ADJ: fine adjustment of output voltage. - Working Temperature: 0~40. - Humidity: 0~95% Non-Condensation. - Protections: overload/ over voltage/ short circuit Cooling by free air convection(Not suggest for use in bathroom). - quality with high efficiency and reliability for durable use. - Easy to use with highly working performance. - Widely used in Industrial automation, LED display, communications, etc.
