Elma offers AC and DC horizontal enclosures in 2U and 5U heights and a DC-only version in 4U height. They include a wide range of backplane, shelf management,and other options. Cooling is achieved via 2 x 170 CFM fans in a side-to-side airflow configuration. The fan tray and fan filter are separately removeable. The units have been optimized via backplane signal integrity studies and chassis thermal simulation.

FEATURES:
– Compliant to PICMG 3.0 specification
– 4U x 444mm x 385mm (H x W x D)
– 5 slot replicated mesh backplane
– Cooling side to side ( 2 x 170 CFM fans)-
– Dual-48VDC input terminals
– Front and rear ESD jack
– Shelf manager optional
– Customization available

This 5U AdvancedTCA Chassis features full redundancy with dual redundant fan trays, shelf managers, and A/C power supplies. The shelf managers and A/C power is optional. Side-to-side cooling is achieved via a plug-in fan tray with dual 170 CFM fans with PWM (pulse width modulation) control on each side of the card cage. The redundant push/pull configurations of the fans offer higher levels of reliability.
The new N+1 version offers two 700W or 1200W power supplies as well as optional dual shelf management integration. The chassis is ideal for designs that need the high-performance and functionality of ATCA, but prefer power supply options.

FEATURES:
– 19″ rack mount, fully compliant to PICMG 3.0
– 5U H x 444mm W x 385mm D
– Rugged steel Construction
– Fits into Zone 4 Seismic Rack (NEBS 3)
– 5 slot full mesh backplane connectivity
– Single or dual 700W AC input PSU providing 48V @ 15A
– Dual fan trays on each side of the card cage
– Side-to-side cooling in push-pull configuration, redundant cooling
– Single or dual pluggable ATCA Shelf manager optional

The 2U ATCA chassis features a 48V DC input or an option for AC input up to 500W. This design makes prototyping and development much easier as the unit can be plugged into a conventional wall outlet (ATCA standardly uses 48V direct and does not have power supplies.) Although ATCA is geared towards the telecom central office market, Elma’s unique A/C units allow much more flexibility and are used in a wide range of highend applications. It incorporates slim-line power supply (4HP high) that saves space. The power supply can also be reduced to 250W output by using a smaller version. A single removable fan tray and filter comes standard, with an option for dual fan trays.

FEATURES:
– Compliant to PICMG 3.0 specification
– Lowest profile in the industry (uses 33% less rack space)
– A/C input or up to 500W 48V D/C output options
– Side-to-side cooling
– Point-to-point mesh backplane in 2-slot size
– Switch cards are not needed for prototyping
– Optional slim-line 4HP power supplies
– Single or dual IPM Sentry shelf manager (optional)
– Customization available
