Westermo products are developed with four different types of casing. DIN-rail | Table top | Rack | Mini
Power supplies
To meet customer requirements Westermo units can be equipped with several different types of power supplies. The following power supplies are standard for Westermo products.
12-36 V DC 36-55 V DC 115 V AC 230 V AC
Table Top
Newer Westermo products are equipped with a primary switched power supply which gives possibilities to handle both AC and DC power supply with the same unit. Products supporting the primary switched power supply are introduced in two versions, LV (low voltage) and HV (high voltage). The LV and HV equipment supports the following voltage ranges.
HV: 95-240 V AC 110-240 V DC +10%
LV: 12-45 V AC 12-55 V DC +10%
For different power requirements please contact Westermo.

Configuration
Simplicity regarding configuration is an important issue for Westermo. With most of the products it is not necessary to use special programs or tools to configure a modem from Westermo. Westermo modems are developed for configuration by DIP-switches and field configuration is easily made with for example a normal screwdriver. This is the same for simple short haul modems and more advanced products like telephone or ISDN-adapters.
DIN-rail
2- or 4-wire twisted pair For 2- or 4-wire applications in industrial environments we recommend the use of cables with at least a 0,2 mm2 cross-section and with a capacitance of between 40-80 pF/m. Use shielded cable in exposed industrial environments and unshielded cable in less exposed areas and office environments. A shielded cable often results in a higher capacitance and, thereby, a lower maximum transmission speed.
Mini
Fibre optic cable
For indoor installations with fibre optic cables use flame-proofed type with a cord free from halogen. For outdoor installations use fibre cables which are water and UV-resistant.
