FAQ

• What is a "sourcing" output?
  It provides the positive voltage (+V) to the load. The load's other side must be connected to the common (ground).
• Can I use this module with 12V DC devices?
  Yes, the 5-50V DC range allows use with 12V, 24V, or other DC voltages within that range.
• What happens if I exceed the 8A total current?
  It may cause the module to overheat or fail. Always calculate the sum of all active output currents to stay within the 8A limit.
