Pilz PILZ-837390 is a protection unit designed for 3-phase voltage monitoring, including overvoltage and undervoltage monitoring functions. It is suitable for DIN rail mounting and operates within an ambient air temperature range of -15 to +55°C. The unit has a net height of 87 mm and supports safety output contacts ratings from 0.1A to 5A at 240Vac (AC-1; 1200VA) and 2A at 230Vac (AC-15). Connection is facilitated through fixed screw terminal connections. The supply voltage requirement is 102-132Vac (120Vac nominal) within the S3UM sub-range. Dimensions include a width of 22.5mm and a degree of protection rated at IP40. It operates across a frequency range of 40-400Hz and is housed in a PPO material. Designed for a 3-phase (3AC) input network with a rated voltage for measuring at 440/480Vac, it has a net width of 22.5 mm and consumes 1.5 W of power. The net depth is 122 mm. Operating modes include fault latching or non-latching and normally energized or de-energized modes. It can be stored in temperatures ranging from -40 to +85°C. The unit features 1 x delayed auxiliary output (SPDT-NO/NC contacts; 0.1-5A 240Vac AC-1 resistive load; 0.5-10s time-delay selectable) for digital outputs, 1 x analog input for L1-L3 voltage measurement, and digital inputs for 1 x automatic reset and 1 x switching commutation. Protection functions cover undervoltage, overvoltage, phase sequence, phase failure, and asymmetry.
