PSSI 54 Series ESD Cabinets - high density static safe storage cabinets for circuit boards. 

PSSI 54 Series Double Bay ESD cabinets are high density static safe storage cabinets for circuit boards. Each 54 Series ESD cabinet is 82" H by 54" W. Model 54-14 is 14" D and Model 54-21 is 21.75" D. The 54 Series ESD cabinets are the ideal choice for digital switching, facility and private line offices, and major computer centers.

PSSI's patented static dissipative shelving system accommodates a wide range of circuit board sizes. The adjustability of the PSSI shelving system provides the highest density of variable size circuit boards compared to other circuit board storage cabinets. These ESD static safe cabinets can safely store packaged or unpackaged circuit boards (see Specifications: Shelving). In addition to circuit board storage, these static safe cabinets also provide protection from theft, fire and unauthorized entry.

• High density storage for large quantities of circuit boards
• Easy access for inventory control and rapid bar code scanning
• Infinitely adjustable static dissipative shelves to accommodate multiple size and shape printed circuit boards
• Protection from theft, fire and unauthorized entry

PSSI Models 54-14 and 54-21 ESD cabinets include these exclusive features:

• Multiple Central Office ground points
• Multiple wrist strap attachment points for simultaneous access
• Optional PWGM tester provides continuous wrist strap and ground monitoring
• Earthquake resistant design with optional frame
• Integrated levelers for easy, proper installation
• Three-point locking bi-fold doors for security and easy access protrude less than 12" (305 mm)

Model 54-14 & 54-21 static safe cabinets have two sections, which can be used independently for circuit board storage and other ESD sensitive inventory. Model 54-14 can store circuit boards up to 10.25 inches (260 mm) deep and Model 54-21 can store circuit boards up to 18 inches (457 mm) deep. PSSIs patented, infinitely adjustable, static dissipative shelves enable high density protective circuit board storage. The 54 Series protective storage cabinets are the ideal choice for digital switching, facility and private line offices, and major computer centers. Customizing accessories are available for storage of packaged circuit boards, computer tapes, data cartridges, disc packs, data printouts, and test equipment.

Models 54-14 & 54-21 protective storage cabinets can be requested without standard shelving.
Model 54-14A & 54-21A static safe cabinets are available to customize according to your specific need (please see Customizing Accessories). Customizing Accessories are available for storage of packaged circuit boards, computer tapes, data cartridges, disc packs, data printouts and test equipment.

Patented, Static-Dissipative Circuit Board Shelving PSSI's patented static dissipative shelving system accommodates a wide range of circuit board sizes. Static dissipative shelving is mounted to stainless steel tracks to protect sensitive circuit boards from ESD by controlling the rate of electrical flow through each shelf to ground. Each shelf is constructed of a specially formulated static dissipative polymer with a surface resistivity 106-109 ohms per square. The grooved design on both the top and underside of each shelf allows for easy insertion and removal of circuit boards. The adjustability of the PSSI static dissipative shelving system provides storage for the highest density of variable size circuit boards compared to other circuit board storage cabinets on the market. PWGM Wrist Strap Tester/Monitor (optional) To assure proper ESD procedures, an optional personnel wrist strap tester and ground continuity monitor (PWGM) is available and can be included in each cabinet. Conveniently located in the cabinet centerpost, the PWGM easily verifies that a technician's wrist strap is making a proper ground and remains correctly connected. The PWGM can also be connected to the central ground system. The PWGM provides an audible and visual alarm if the technician's wrist strap fails or inadvertently disconnects, or if the cabinet ground should disconnect from the central ground system.

The chart below will assist you in determining the number of shelves required for the quantity of spare circuit boards being stored.
The 54-14, and the 54-21, cabinet has four compartments. There are two compartments on each side of the cabinet center post.
Each compartment will have a variable number of vertical chambers determined by the height of the circuit boards in each chamber.
There are two formulas at the bottom of the chart to assist you in determining:

 a. The number of circuit boards per chamber, and

 b. The number of shelves required

Horizontal Storage Formula  10" ÷ Width of Board =  Number per chamber.

Notes:

1. Horizontal shelf formula: ROUND UP to nearest half or whole number.
2. Vertical shelf formula: ROUND UP to nearest fraction.
3. For TOTAL storage capacity by compartment:
   Multiply the vertical chambers by the number of boards per chamber.
4. Circuit board storage calculations are within + or –10%.
5. Model 54-14 for circuit boards up to 10-1/4" in length.
   Model 54-21 for circuit boards up to 18" in length.
6. MAXIMUM horizontal circuit board storage: 16 circuit boards per chamber.
