Thermoelectric cooler SI Subseries series

single-stage

The «S-Series» is a line of the single stage thermoelectric coolers which are able to provide maximum temperature difference up to 76 (K). These series includes more than 1200 standard TECs models. Here you will find TECs with performance characteristics ranges as shown in the table. SI – TECs with increased cooling capacity; Imax (A) 0.55 - 9.7 Umax (V) 0.48 - 11.5 Qmax (W) 0.27 - 62 Height (mm) 1.65 - 4.1 Overall dimension (sq.mm) 1.6 x 3.2 - 21x21 «S-Series» is divided to the next subseries: SS – standard rectangular TECs; SL – linear TECs; SR – round TECs; SH – TECs with holes; SI – TECs with increased cooling capacity; Parameter - Definition Imax, (A) - TEC current at ΔTmax Umax, (V) - TEC voltage at ΔTmax ΔTmax, (K) - Maximum temperature difference between TEC cold and hot side (I=Imax, Qmax=0) Qmax, (W) - Maximum TEC cooling capacity (I=Imax, ΔT=0) Th, (K) - TEC hot side temperature H, (mm) - TEC height Top=AxB, (mm) - Dimensions of the TEC cold side Bottom=CxD, (mm) - Dimensions of the TEC hot side General Notes: All TEC performance characteristics given for 30°C in vacuum All TEC dimensions given in millimeters To estimate TEC cooling capacity (Q ) at ΔT different from ΔTmax use equation Q=Qmax (1-ΔT/ΔTmax) To estimate TEC temperature difference (ΔT) at Q different from Qmax use equation ΔT = ΔTmax (1- Q/Qmax)
