1. Model Breakdown

DDC: Digital Drive Controller

01.2: First generation, hardware version 2 (heat dissipation / EMI optimization)

N050C:

N = Natural convection (no fan)

050 = 50A continuous output current

C = Low noise (low noise version)

DA02:

DA = Analog interface (pure analog command ±10V)

02 = Function code 02 (enhanced analog quantity)

01: Hardware revision version 01

Full model usually includes -FW (pre-installed firmware): DDC01.2-N050C-DA02-01-FW
