Higher power capability for UPS
DIN rail mounting power supplies with UPS capability are popular within the security industry and other sectors where critical equipment must continue operation during a brief mains failure.
Sunpower UK has been meeting this need with their Mean Well DRC-40 and DRC-60 Series, which have been receiving outstanding market feedback and highly positive customer evaluation since their launch.
Sunpower has now extended this family by announcing their new Mean Well which delivers similar functionality by announcing their new Mean Well DRC-100 Series, which delivers similar functionality but with an output power rating elevated to 100W. The new Series, which has been introduced in response to the security industry’s demand for higher power capability, currently consists of two models with different output voltage levels. Both units are highly reliable and can be assembled onto TS35/7.5 or TS35/15 DIN rails within an industrial cabinet.
The units both have universal inputs which accept 90 – 264VAC or 127 - 370VDC. The DRC-100A has two 13.8V outputs, and DRC-100B delivers 27.6V from its two outputs. These are ideal for 12V and 24V batteries respectively. With efficiencies up to 89%, both models feature a fanless design with cooling by free air convection and a wide operating temperature range of -30 to +70°C. Protection functions include overload, over-voltage, battery low cut off and fused battery reverse polarity safeguard; the units also have relay contact alarm signals for AC OK and battery low. An LED indicator shows Power On status.
An external 12V or 24V battery can be connected to the secondary output contacts provided on the power supplies. During normal operation with AC mains present, the power supplies rectify and filter the incoming AC to supply DC power to the load and charge the battery. During a mains failure, the battery ensures continued power to the load until it is discharged or mains power is restored. The battery charger floats on the rectifier’s DC output; this ensures seamless transfers between rectified mains and battery supplies, and uninterrupted power to the load.
“Not only security installations, but also systems for emergency lighting, alarms, central monitoring, access, communications and many other applications frequently require uninterrupted, adequate power to ride through a mains blackout” commented Andy Wall, CEO of Sunpower UK Ltd., “and the Mean Well DRC-100 products allow systems integrators and installers to achieve this easily and reliably. The units carry UL/CUL/TUV/CB/CE approvals, and all have a three-year warranty.”
