VMAX BUS TIPS

V-MAX BUS SYSTEM in VESTA panels tips:

GENERAL RULES:

• From one device or bus start to the next, no more than 300 metres may be exceeded.

• Take into account the current required for the system (use calculator or consumption table of the devices).

• Take into account the voltage drop (calculator) If there is a voltage drop, a power supply or isolator-amplifier can be used

• The limit of the BUS system at distance level will depend on the consumption and voltage at each point, if a sufficient current and voltage is guaranteed at each device, the system will operate correctly.

CASE 1: ONE LINE OF BUS

CASE 2: TWO LINES OF BUS (STAR)

CASE 3: TREE LINES

CASE 3A. WITH ISOLATOR (Recomended for this CASE)

CASE 3B. WITH NO ISOLATOR (TIP: Place resistors in the longest BUS sections.)

CASE 4: FOUR LINES OF BUS
