DC UPSs Optimized for Optical Network Terminals
Bourns, Inc. announced three new uninterruptible power supplies (UPS) that are compact, feature-rich dc power supply and battery back-up solutions. The latest UPS devices from Bourns are optimal DC power supply and battery back-up devices for 12Vdc powered Optical Network Terminals (ONTs), and are also well-suited for any 12Vdc application where dc power and battery back-up is required.
Offering small size for placement flexibility and designed for high reliability, Bournsâ€™ latest UPS models provide three alarm features, ONT reset and cold start functions along with overvoltage protection and EMI/RFI filtering. These UPS devices utilize Lithium-Ion battery technology with integrated battery management systems which helps assure long-life and safe operation.
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, the Model MX1236 Series UPS 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 / 3.0A (36W).
During a power failure, the replaceable Lithium-Ion battery pack is capable of providing up to 10 hours of back-up capacity at 8 Watts. UL Listed, the BournsÂ® Model MX1236 Series provides the small size and flexibility needed to support todayâ€™s ONTs, Optical Network Units (ONUs), Fiber to the Home (FTTH), security systems, and more. Orderable 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 BournsÂ® Model MP1218-L1 Series Indoor Micro UPS provides a constant supply of dc power and additionally provides battery back-up power in case of an electrical power outage. 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). During a power failure, the replaceable battery pack is capable of providing up to 6 hours of back-up at 8 Watts 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. The UL Listed Model MP1218-L1 Series delivers the small size and flexibility required for current GPON installations. Model MP18-L1 replacement batteries are also available.
A related new product is the Model MP1218-P Series Indoor Micro Power Supply. It is designed and intended for 12-Vdc Optical Network Terminals but can be used in any 12-Vdc application where a dc power supply is required such as VoIP, FTTH and video. A model with seven-conductor Vdc and telemetry is available. The MP1218-P is UL Listed.
As a pricing reference, the BournsÂ® 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 in single piece quantities. The new models are available now and are RoHS compliant.
