Product Manual：

Alstom L54E1100CZ00 CPRM1 Printed Circuit Board
(Alstom Microrec K4.1 series thyristor power control/trigger board)
1. Basic Information
Model: L54E1100CZ00
Abbreviation: CPRM1
Brand: Alstom (now GE Alstom)
Series: Microrec K4.1
Type: Single phase power regulation/thyristor trigger control board
2. Core functions
Single phase power regulation: Control the conduction angle of thyristors to achieve precise regulation of 0-100% single-phase AC power.
Trigger pulse output: Send a synchronous trigger signal to the thyristor (SCR) to drive the power unit.
DC bus voltage control: Monitor and stabilize the DC side voltage to ensure the safety of the power circuit.
Pulse monitoring and diagnosis: In conjunction with the MDMI1 module, monitor the triggering pulse status of thyristors and issue fault alarms.
Local data processing: Share the load of the main controller and independently handle closed-loop control logic.

3. Key parameters
Adaptation system: Alstom Microrec K4.1, ALSPA old model control system
Control object: single-phase thyristor rectifier/regulator
Signal interface: pulse triggered output, voltage/current sampling input, communication bus
Working power supply: 24VDC ± 10%
Environmental temperature: 0 ° C~+55 ° C (industrial grade)
Installation: Standard rack slot installation
Status: Discontinued production of scarce spare parts, mostly for refurbishment/second-hand supply
4. Typical applications
Industrial heating furnaces and heat treatment equipment
Rail transit auxiliary power supply system
Precision power supply, electrochemical rectification
Power control of wind/photovoltaic converters
