Bourns unveils three uninterruptible power supplies (UPS) that are compact, feature laden, and highly reliable. The power sources are optimal dc power supply and battery back-up devices for 12 Vdc powered Optical Network Terminals (ONTs), and are also well-suited for any 12 Vdc application where DC power and battery back-up is required.
The Model MX1236 Series Indoor MicroFlex UPS offers a unique low-profile design where the DC supply and Lithium-Ion battery pack can be stacked, and can accept up to three battery packs for additional back-up capacity. In addition, it is capable of accepting 50-/60-Hz ac power inputs from 100 to 240 Vac. This DC power supply provides a nominal dc output of 12V/ 3A (36W). During a power failure, the replaceable Lithium-Ion battery pack is capable of providing up to 10 hours of back-up capacity at 8W. Options are: Model MX1236-L2-C7 which includes a power supply, UPS battery and relays for Vdc and telemetry output and Model MX1236-P-C7 which includes a power supply and relays for Vdc and telemetry output. Model MX36-LC is a replacement battery.
The Model MP1218-L1 Series Indoor Micro UPS provides a constant supply of dc power and additionally provides battery back-up power. It can accept 50-/60-Hz ac power inputs from 100 to 240 Vac. The DC power supply provides a nominal DC output of 12V /1.5A (18W). The replaceable battery pack is capable of providing up to 6 hours of back-up at 8W load. Output cabling options include a 7-conductor 12-Vdc power and telemetry as well as a 2-conductor barrel type connector for dc power only.
A related unit, the Model MP1218-P Series Indoor Micro Power Supply is designed for 12-Vdc Optical Network Terminals but can be used in any 12-Vdc application where dc power is required such as VoIP, FTTH and video. A model with seven-conductor Vdc and telemetry is available.
As a pricing reference, the Model MX1236 is list priced at $184, Model MP1218-L1 is list priced at $140, and Model MP1218-P is list priced at $70 each. For more details, visit http://www.bourns.com/products/surge-protective-devices
