System compatibility

91010378 belongs to RELIANCE DM100 series AC power module.

Installed into Reliance DM100 AC drive cabinet,works with drive control board,pulse trigger board and auxiliary power supply board.

It is the main power conversion unit for DM100 AC variable speed drive.

Commonly used for old industrial AC drive equipment maintenance and spare replacement.

Function

91010378 is dedicated AC power module for RELIANCE DM100 AC drive system.

Complete three-phase AC rectification and power inversion for motor drive.

Receive trigger pulse signal from control board to adjust output frequency and voltage.

Built-in overcurrent,overvoltage,overtemperature hardware protection circuit.

Detect power unit fault and send alarm signal to drive control system.

Internal power semiconductor components for high-power motor energy conversion.

Onboard temperature sensor and current sampling circuit for real-time monitoring.

Installation

Power off the whole drive cabinet and cut main three-phase power supply.

Mount 91010378 module inside drive cabinet and fasten fixing bolts.

Connect three-phase AC input,motor output wiring and pulse signal cable.

High power main circuit wiring must be separated from low voltage control signal cable.

Power on system,inspect input and output voltage.

Test overcurrent and overtemperature protection response.

Interface

Three-phase AC input terminal,motor output terminal,pulse signal connector,temperature & current sampling port,status & fault LED indicators.

Feature

RELIANCE 91010378,DM100 series high power AC drive power module.

Integrated rectifier and inverter power section for AC variable frequency drive.

Multiple hardware protection to prevent power device damage.

Built-in sampling circuit for current and temperature real-time monitoring.

Metal housing with heat sink for heavy-duty industrial environment.

Discontinued obsolete module,supply only for old automation drive system spare replacement.

Suitable for metallurgy,paper-making heavy-duty AC drive production line renovation.

Diagnostic

Drive report overcurrent fault:power module IGBT damage or short circuit;

No motor output:missing trigger pulse or internal power device failure;

Overtemperature alarm:heat sink fouling or cooling fan abnormal;

Random trip under load:power device aging or current sampling fault;

Power indicator no lighting:three-phase input power missing.

Product Brief
