Product Description

The Siemens SIPLUS S7-1500 PM1507 6AG1333-4BA00-7AA0 is a dedicated 24VDC 8A load power supply for SIMATIC S7-1500 PLC systems operating in harsh industrial environments. Based on the standard 6EP1333-4BA00 with conformal coating, it delivers 192W of regulated DC power for large S7-1500 configurations with extensive I/O modules, communication processors, and high-current backplane loads — with full environmental hardening for the most aggressive industrial conditions.

Key Features

SIPLUS extreme conformal coating (IPC-CC-830A Class A, EN 61086 Class 2) protects against H2S, Cl2, NH3, 100% RH condensation, frost, salt mist (EN 60068-2-52 severity 3), sand, dust, and biological contaminants (mold, fungi, spores)
Wide operating temperature: -40 to +70 °C (storage/transport -40 to +85 °C)
Auto-ranging input: 85-132 V AC / 170-264 V AC at 45-65 Hz
Stabilized 24VDC output with tight ±1% static regulation and <50 mVpp ripple
Electronic short-circuit protection with automatic restart — 70 ms overload capability at 35 A
Overvoltage protection clamps output below 28.8 V
90% efficiency — the highest in the PM1507 series — minimizes heat in sealed panels
Mounts directly on S7-1500 mounting rail for seamless PLC rack integration
SELV galvanic isolation per EN 60950-1, EN 50178, and EN 61131-2
EN 55022 Class B EMI compliance
1.36 million hours MTBF at 40 °C
Up to 6,000 m installation altitude with derating

Applications

This load power supply is purpose-built for large SIMATIC S7-1500 PLC installations in the harshest industrial environments — chemical processing plants with corrosive gas exposure, offshore oil and gas platforms subject to salt mist and condensation, mining operations with dust, vibration, and temperature extremes, and outdoor container-based automation systems with wide temperature swings. The 192W rating supports the CPU, multiple communication processors (PROFINET, PROFIBUS, Ethernet/IP), and fully loaded I/O racks with high-current modules. The 90% efficiency reduces waste heat in sealed enclosures, while the 1.36M hour MTBF delivers the reliability demanded by continuous process control applications.
