Schneider DNP 205 | TSX Compact Power Supply

The Schneider DNP 205 provides reliable DC power for TSX Compact automation platforms. This power supply module converts 100-240 V AC input to 5 V DC output. It delivers up to 45 W of total output power for rack-mounted modules. Weighing only 0.55 kg, the Schneider DNP 205 fits into any standard TSX Compact rack slot. Its dimensions measure 110 mm x 70 mm x 95 mm.

Output Specifications and Load Capacity

The Schneider DNP 205 supplies 5 V DC at 7 A for logic and backplane operations. It also provides 24 V DC at 0.3 A for auxiliary field power needs. The module achieves 82% typical efficiency for reduced heat generation. Moreover, the Schneider DNP 205 includes built-in overload and short-circuit protection. Consequently, it automatically shuts down during fault conditions and recovers when the fault clears.

Input Specifications and Energy Storage

The Schneider DNP 205 accepts a wide input voltage range from 85 V AC to 264 V AC. This module also supports 47 Hz to 63 Hz frequency variations for global compatibility. It features no internal battery for complete maintenance-free operation. The Schneider DNP 205 includes 680 µF of output capacitance for energy storage. This capacitance provides 15 ms of hold-up time during input power interruptions. Therefore, your PLC continues running through brief power dips and voltage sags.

Installation and Application Details

The Schneider DNP 205 mounts into the designated power supply slot of any TSX Compact rack. This module supplies power to all other modules in the same rack. Connect the line (L), neutral (N), and protective earth (PE) terminals correctly. The Schneider DNP 205 requires no external cooling fan for normal operation. It suits small to medium TSX Compact systems with multiple I/O modules. Thus, this power supply delivers stable DC power for reliable industrial control applications. Replace the unit only if it fails, as it contains no user-serviceable parts inside.
