5.2.2 Circuit Diagram without ASPS Assembly
For IT systems (voltage supply: Isolated neutral, user protection: grounding (French: Terre),
Gebrüder Martin provides power modules (A1.2) with fuses (F1 and F11) for both voltage-carrying
leads (L1, L2). For standard systems with grounded neutral conductor, the power modules (A1.1) with fused
phase (only F1 for L) must be used.
Power module SMPS 36/9 S3 U L (-N)
100–240 VAC, 50–60 Hz, Input current 3.5–1 A
Output Power max. 290 W (28–36 VDC)
Rotary potentiometer for output voltage
Adjustment across a range of
28–36 VDC, see section 5.2.5 “Adjusting the
Voltage”, page 24
F11 for IT systems only (isolated power supply)
Connector Designation Fuse rating
X1 Input 100–240 VAC, 50–60 Hz F1/F11
X3 Output 28–36 VDC T 5 AH, 250 V
