The Schneider Electric MTN6513-1202 is a SpaceLogic KNX power supply rated at 640 mA for medium-to-large KNX segments. It provides regulated 30 V DC on a choked KNX bus output plus a separate 30 V DC auxiliary output for IP interfaces, logic controllers, or panel auxiliaries.

Two identical units can operate in parallel to double bus current on one line. A floating signaling contact relays diagnostic status to BMS or alarm inputs. For higher capacity use MTN6513-1201 (1280 mA); for smaller lines MTN6513-1203 (320 mA) or bus-only MTN684064.

Key Features — 640 mA with Dual Outputs

Power and Expansion

• Bus output: 640 mA at 30 V DC with integrated choke.
• Parallel operation: Two MTN6513-1202 units → up to 1280 mA on one line.
• Auxiliary output: 30 V DC for peripherals (e.g. MTN6502-0105, LSS100100).
• Signaling contact: Remote monitoring of supply health.
• Protection: Short-circuit and overload protection on outputs.

Applications and KNX Integration

• Standard commercial lines: Typical choice for mixed sensor, actuator, and UI counts with MTN6700 and MTN6300 devices.
• Parallel upgrade: Add a second MTN6513-1202 when device count grows without replacing infrastructure.
• IP backbone: Power MTN6500-0103 and tunnel with MTN6502-0105 on the same line.
• Line structure: Segment with MTN6500-0101 couplers; schedule with MTN6606-0008.

Choosing MTN6513-1202 vs MTN684064

Choose MTN6513-1202 when you need auxiliary 30 V, signaling contact, and parallel expansion. Choose MTN684064 for a compact, cost-effective 640 mA bus-only supply with bus-reset button.
