The BLM-2202U-LP120-7 operates as a compact DC-DC converter, converting a wide range of input voltages (24V ±20% DC) into a stable 7V DC output—ideal for powering microcontrollers, sensors, and communication modules. What distinguishes it is its advanced filtering technology, which suppresses electromagnetic interference (EMI) both from incoming power lines and generated by the converter itself, preventing signal corruption in nearby electronics. The converter features a low-profile design (just 12mm in height) that fits into tight spaces, such as stacked control panels or mobile robotics systems, without sacrificing thermal performance. It integrates seamlessly into existing power architectures via screw terminals, with built-in protection against overvoltage, overcurrent, and short circuits—ensuring it shuts down safely during faults to protect connected equipment.
BLM-2202U-LP120-7
The BLM-2202U-LP120-7 also includes remote sense functionality, allowing it to compensate for voltage drops in long wiring runs, ensuring the load receives precise 7V even at the end of extended cables.

Main features and advantages:
Choosing the BLM-2202U-LP120-7 delivers tangible benefits for power-sensitive systems. Its high efficiency (up to 96%) minimizes heat generation, reducing the need for additional cooling in crowded cabinets—a key advantage in space-constrained environments like portable test equipment or compact robotics. The converter’s wide operating temperature range ensures reliability in extreme conditions, from freezing warehouse automation systems to hot steel mill control panels. Engineers will appreciate the remote sense feature, which eliminates the need for oversized wiring to compensate for voltage drops, cutting material costs and installation time. Most importantly, the BLM-2202U-LP120-7s robust protection mechanisms prevent catastrophic failures, ensuring downstream components like sensors and microcontrollers remain undamaged during power anomalies—directly reducing repair costs and unplanned downtime.
Application areas:
The BLM-2202U-LP120-7 excels in applications where stable low-voltage power is critical. In semiconductor manufacturing, it powers precision motion controllers for wafer-handling robots, where voltage fluctuations could cause submicron positioning errors, compromising chip quality. In renewable energy systems, such as solar inverter control boards, it converts battery voltage to stable 7V for data loggers and communication modules, ensuring uninterrupted transmission of performance data to grid management systems. The converter also performs reliably in mobile robotics, where its low profile and shock resistance (up to 50G) make it ideal for powering onboard sensors in automated guided vehicles (AGVs), ensuring consistent operation even on rough factory floors. In each case, the BLM-2202U-LP120-7 provides the power stability needed to maintain precision and uptime.
Related products:
Before installing the BLM-2202U-LP120-7, ensure the mounting surface is clean and flat to maximize thermal transfer—apply the included thermal pad between the converter and chassis to dissipate heat effectively. Verify that input wiring is sized for the maximum current (120A) to prevent voltage drops and overheating; 4AWG (25mm²) wire is recommended for runs exceeding 1 meter.
During setup, use the remote sense terminals to connect directly to the load, ensuring the converter compensates for wiring losses. For systems with high inrush current (e.g., motor drivers), add a soft-start circuit to prevent tripping the overcurrent protection. During maintenance, inspect input/output connections quarterly for signs of corrosion or loosening, especially in vibration-prone areas, and check the thermal pad annually for degradation—replace if hardened or cracked to maintain cooling efficiency.
