Lambda / TDK / EMI GENH 40-19 / GENH40-19

The TDK-Lambda GENH 40-19 is a 760 W programmable DC power supply from the Genesys series, delivering 0 to 40 V and 0 to 19 A for OEM, industrial, laboratory, and field-service applications. This 1U rackmount/benchtop unit features active power factor correction, dual communication interfaces (RS-232 and RS-485), and optional LAN, GPIB, USB, and isolated analog control. Automatic CV/CC crossover, comprehensive front-panel programmability, and selectable protection modes – including over-voltage, under-voltage, and foldback – enable flexible deployment across automotive, semiconductor, medical, aerospace, and test environments. ## Technical Specifications • **Input:** 85 to 265 Vac, single-phase, 47 to 63 Hz
