The Schneider Electric MTN6513-1201 is a SpaceLogic KNX power supply delivering up to 1280 mA bus current for large KNX lines (up to ~256 devices). It generates regulated 30 V DC SELV with an integrated choke on the KNX output and includes a second 30 V DC auxiliary output (unchoked) for IP routers, displays, or other peripherals.

A floating signaling contact reports operation, overload, and power-failure states to external monitoring. Mains input is 180–264 V AC at 50/60 Hz. For medium lines use MTN6513-1202 (640 mA) or the compact MTN684064; for small zones see MTN6513-1203 or MTN684032.

Key Features — High-Capacity Bus Power

Outputs and Monitoring

• KNX bus output: 30 V DC with integrated choke — up to 1280 mA combined rating.
• Auxiliary output: 30 V DC (unchoked) for additional loads in the same cabinet.
• Signaling contact: Floating contact for remote diagnostics (run, overload, failure).
• Protection: Short-circuit, overload, and over-voltage protection.
• Choke: Decouples DC supply from data telegrams on the twisted pair.

Applications and KNX Integration

• Large commercial lines: Power dense actuator banks such as MTN6700-0104 / MTN6700-0304 on a single segment.
• Auxiliary loads: Feed MTN6500-0103 IP routers or MTN6215-0410S auxiliary DC from the 30 V output.
• Multi-line sites: One PSU per line; couple areas with MTN6500-0101.
• Scheduling: Centralise time programs with MTN6606-0008 year time switch.

Choosing MTN6513-1201 vs Other PSUs

Use MTN6513-1201 when a single line needs up to 1280 mA with auxiliary 30 V and signaling. For 640 mA with parallel expansion, choose MTN6513-1202. For simpler bus-only supplies without aux output, see MTN684064 (640 mA) or MTN684032 (320 mA).
