其他信息
The POWER 3AC 48-10 is a three‑phase AC/DC DIN‑rail power supply delivering 480 W at 48 VDC with an adjustable output range from 48 to 56 V and a rated current of 10 A, making it ideal for 48 V control, I/O, and drive systems. With a wide input range of 320...600 VAC (450...850 VDC), it supports global three‑phase grids and robust industrial environments. The unit achieves up to 94.5% efficiency, operates from −30 to +70 °C (start‑up at −40 °C), and provides a 20 ms hold‑up time to ensure stable DC power under fluctuating mains conditions. Integrated protection functions including over‑voltage, over‑current, short‑circuit, and over‑temperature with auto‑recovery, as well as enhanced conformal coating and a built‑in DC OK relay contact, increase system availability and diagnostics capability. For higher power requirements, up to four units can be connected in parallel with active current sharing to achieve up to 1920 W (3+1), while compliance with IEC/EN/UL 61010 and IEC/EN/UL 62368 safety standards and EMC class B emissions supports use in industrial control, semiconductor manufacturing, and renewable energy applications.
Parallel Use
POWER 3AC 48-10 has built-in active current sharing function and can be connected in parallel, up to 4 units, to provide
higher output power as exhibited below :
1. The power supplies should be paralleled using short and large diameter wiring and then connected to the load;
2. When parallel use, ensure that all P+ on the signal connectors of each power module are connected together,
and all P- also connected together;
3. Difference of output voltages among parallel units should be less than 0.2V.
内置浪涌电流限制
浪涌电流限制电路采用热敏电阻 (POWER 1AC 24-5)、晶闸管技术 (POWER 1AC 24-10) 或有源功率继电器电路 (POWER 1AC 24-20 / 48-10)。
带电位器的可调输出电压
顺时针转动内置电位器增加输出电压， 逆时针转动电位器则降低输出电压。
功率提升 150
5 秒钟 150% 的功率提升意味着电源可以在短时间内，特别是在 5 秒钟内，暂时提供其额定输出功率的 150%。当连接的负载偶尔需要比正常工作条件更高的功率时，该功能就非常有用。
并联操作
您可以在并联操作模式下使用电源以提高可用性，请在此应用中使用我们的功率二极管模块。
超薄尺寸
超薄尺寸，可以节省柜内空间
DC OK LED
如果输出电压降低，DC OK LED 将关闭。 在“正常”输出电压条件下，LED 亮起。
