LC1D95M7

Schneider Electric LC1D95M7 is a magnetic contactor from the Deca sub-range, featuring screw connections and three poles (3P; 3NO). It has a rated current of 125A (AC-1) and 95A (440Vac; AC-3), with a mounting mode designed for DIN rail installation. The net width of the contactor is 85 mm, and it offers a degree of protection rated at IP20. The control voltage (AC) ranges from 176-242Vac (220Vac nom.; 50Hz; 0.8...1.1 x Uc) to 187-242Vac (220Vac nom.; 60Hz; 0.85...1.1 x Uc), with a rated operating voltage (Ue) of 1000 V. It includes 1 normally open (NO) auxiliary contact and 1 normally closed (NC) auxiliary contact, both of the instantaneous type (1NO+1NC). The rated impulse voltage (Uimp) is 8 kV. This contactor is capable of handling rated active power ranging from 25kW (220-230Vac; AC-3) to 55kW (500Vac; AC-3), with specific ratings for various voltages up to 1000Vac. It also supports rated power (HP) for motors from 7.5HP (115Vac; single-phase) to 60HP (575-600Vac; 3-phase), under UL/CSA standards. The mechanical durability of the LC1D95M7 is rated at 4,000,000 operations, and its electrical durability (with load) is rated at 1,200,000 operations. The rated voltage (AC) for phase-to-phase connections is 1000 V.

UBC10.241

PULS UBC10.241 is an Uninterruptible Power Supply (UPS) control module within the U-series, featuring a built-in battery with a 50% power reserve and a green status LED. This module is housed in aluminium and utilizes spring-clamp connections for installation. It measures W123mm x H124mm x D119mm and operates on a supply voltage range of 22.5Vdc to 30Vdc, with a nominal 24Vdc. The rated current is 10A at 22.5Vdc and can reach up to 15A in buffer mode for less than 5 seconds at full output voltage. It supports DIN rail mounting and can operate in ambient air temperatures ranging from 0 to +40°C. The current consumption is 1.1A at a 24Vdc input, and it is designed for DC networks. Visual position indicators include Ready, Buffering, Inhibit, and Replace Battery. Protection functions include output overvoltage protection with a typical 32Vdc and a maximum of 35Vdc, and overload/short-circuit protection with a minimum of 17.9A and a maximum of 21A at load impedance. It is advised not to use the DC-UPS in parallel to increase output power, but paralleling two units for 1+1 redundancy is possible for higher system reliability. The output voltage is regulated at 22.5Vdc in buffer mode with a 23Vdc turn-ON. The efficiency is rated at 0.978 with a 24Vdc input, and the rated power is 360W at 24Vdc and 240W/360W in buffer mode. Power dissipation/losses are 2.9W with a 24Vdc input at 0A output current and 5.5W at 10A output current. Ripple is maintained at 20mVpp across a frequency range of 20Hz to 20MHz at 50Ω. The electrical durability is rated at 137400 hours at 40°C with a 10A output and 24Vdc input, equivalent to 15 years or 131400 hours at both 40°C with a 5A output and 25°C with a 10A output.
