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, Bourns’ 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 Bourns® Model MX1236 Series provides the small size and flexibility needed to support today’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 Bourns® 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 Bourns® 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.
