Press Release Summary:
Helios MiniFLEX line accepts modular rectifiers rated at 250 and 500 watts, enabling units to provide maximum output power ranging from 1,000 to 2,000 watts. MiniFLEX devices can hold up to 4 hot swappable rectifiers or operate with single rectifier installed. They have front accessible connections, built in Low Voltage Disconnect and eight 10 amp fused distribution outputs. Units are 3U tall, 19 in. wide, and 13.2 in. deep.Original Press Release:
Astec Power Introduces The Helios MiniFLEX Family of Telecom Power Solutions
A Compact Solution to the Small System Power Dilemma
CARLSBAD, Calif. - February 25, 2002 - Astec Power, a leading merchant supplier of power conversion solutions, today announced the addition of its new MiniFLEX product family to its extensive lineup of telecommunications power products. The FLEX in its name
stands for configuration flexibility. Modular rectifiers rated at 250 and 500 watts enable the MiniFLEX to provide maximum output power that ranges from 1000 to 2,000 watts. Able to
hold up to four hot swappable rectifier modules, the MiniFLEX can be put into operation with a single rectifier installed. More rectifiers can be added later as the load demanded by the
equipment at that installation grows. In addition to this modularity, the MiniFLEX features "plug and play" simplicity: no float adjustment, front accessible connections, built in Low Voltage Disconnect (LVD) and eight 10 amp fused distribution outputs, making it a cost competitive yet feature rich Telco-grade power solution.
At less than 3U tall (5 inches) the 19 inch wide MiniFLEX can fit into almost any equipment rack. At only 13.2 inches deep, and with overall shelf power densities of more than 2 watts per cubic inch possible, the MiniFLEX is an ideal solution for applications where space is at a premium, such as curbside cabinets, Private Branch eXchange (PBX) boxes, Digital Subscriber Line Access Multiplexers (DSLAMs), Personal Communication System (PCS) Micro-cells, wireless local loop installations and high speed data switch sites.
The heart of the MiniFLEX is the rectifier module. Available in maximum output power ratings of 250 and 500 watts, these modular rectifiers are self-contained, current-limited sources that exhibit constant power behavior at full load. The output voltage of each rectifier module is factory pre-set to -54.5 VDC, with no field adjustment required. The 250-watt module can deliver up to 4.6 amps continuously and features a full universal AC input voltage range of 84 to 264 VAC. The 500-watt module can deliver up to 9.2 amps continuously and features a wide "high line" input voltage range of 176 to 264 VAC. All rectifiers are the same physical size and fit into any modular slot within the MiniFLEX chassis.
From 50 percent to full output power, all of the MiniFLEX rectifier modules perform at greater than 86 percent efficiency, and are power factor corrected to better than 0.98. Each
installed module is forced to share the load with all of the others, which prevents premature "load hogging" induced rectifier failures. Each rectifier also has its own visible operation status indicator LED, and a built in High Voltage Shut-Down (HVSD) trip point of -58.25 VDC. When the rectifiers are correctly inserted into a properly grounded MiniFLEX chassis, the entire installation will meet FCC class B radiated and conducted EMI specifications. And with the wide ambient operating temperature range of -40C to +65 deg C, a MiniFLEX system can be installed outdoors, without the concern of temperature extremes causing it to not operate correctly. Lastly, all rectifier models have demonstrated over 350,000 hours of Mean Time Between Failure (MTBF), which is more than three times the standard Telco requirement.
The MiniFLEX enclosure has built-in, horizontal flowing, forced-air cooling. The intake and exhaust vents are located on the sides of the chassis. This approach ensures adequate airflow without requiring wasted space at the top, bottom, front, or back of the unit; which is a feature that makes this design truly tight space compatible. Built-in battery string connection
points allow the unit to be deployed as a telecommunications power source. The unit's LVD contactor has a test switch and a bypass mode. This enables the contactor's functionality to be
tested and verified without taking the unit out of service. In bypass mode, the unit's load will continue to run on backup power, past the time when the contactor would have disconnected,
in the event that the input AC power remains unavailable. The full complement of remote alarm output signals, and the eight distributed load outputs feature lug-less connections, for ease of installation. The hinged front door allows clear unhindered access to all electrical connections, including AC line, DC load and backup battery string hookup points.
The MiniFLEX meets all major safety and performance requirements, including UL 1950, UL1801, CISPR 950, CSA 22.2 # 950, EN300-386-2, VDE, CE, FCC class B, UL 94, GR1089, and is designed to meet NEBS requirements. Available now, pricing starts at $2,537 per 2,000-watt unit in small quantities.
