Emerson SPMC2402 Controlled Input Rectifier Module

FAQ

Q1: What is the Control Techniques SPMC2402?
A: It is a controlled three-phase input rectifier module for the Unidrive SP drive system.

Q2: What type of rectifier does the SPMC2402 use?
A: It uses a dual half-controlled thyristor bridge, allowing controlled rectification of the incoming AC supply.

Q3: What is the input voltage of the SPMC2402?
A: The rated input is 380–480 VAC ±10%, three-phase, at 50/60 Hz.

Q4: What DC voltage does the SPMC2402 provide?
A: The specified DC output range is approximately 513–648 VDC, depending on the AC input voltage and operating condition.

Q5: What is the output current rating?
A: Available technical listings specify approximately 678 A continuous output and up to approximately 758 A under the specified conditions.

Q6: What is the SPMC2402 used for?
A: It is primarily used as the AC front-end/DC bus rectifier for Unidrive SP inverter modules, especially in high-power drive systems.

Q7: Does the SPMC2402 have built-in soft start?
A: Yes. The SPMC controlled rectifier has integrated soft-start.

Q8: What are the dimensions and weight of the SPMC2402?
A: The unit is approximately 390 × 280 × 220 mm and weighs approximately 17.7 kg. Because this is an older high-power module, packaging and mounting accessories can significantly increase shipping dimensions and weight.
