Details
Meanwell DRS-240-48 is a 240W AC/DC DIN rail type security power supply with 48V0-5A3.85A5-50AH480mVp-p±. The unit could be installed on DIN rail TS-35/7.5 or 15, and accepts the universal input between 90VAC and 305VAC. Except for the primary output, there is an additional charger circuit which will automatically adjust charge current depending on the primary output current. With high efficiency up to 92% and Built-in MODBus protocol, CANBus optional, Meanwell DRS-240-48 is able to work under -30 ℃ through 70℃ with free air convection cooling. Apart from the key protections such as overload protection, over voltage protection, battery low voltage disconnect, and battery reverse polarity protection, Meanwell DRS-240-48 also supplies Form-C contacts and LED indicator alarm signals for AC-fail, battery low, charger circuit fail, and DC-OK to allow easy integration into security systems that meet with local alarm codes. As a result of its longevity, excellent quality and high reliability, Meanwell DRS-240-48 is an ideal power supply solution for industrial applications.
