| Voltage Transducer DCVT-25V10 For the electronic measurement of voltages : DC with a galvanic isolation between the primary circuit and the secondary circuit. VPN = 25 V Preliminary Electrical data VPN VP Vout RIN KN Vd Primary nominal r.m.s. voltage Primary voltage, measuring range Output voltage @ VPN Input Load resistance1) Conversion ratio R.m.s. voltage for AC isolation test, 50 Hz, 1 mn (between primary and measuring circut) 25 + 1.6 .. + 35 10 25 : 10 5.4 kV V V V Features * RCC voltage transducer * Compact panel Mount type RIN=62(VIN(max)-26.6) Remarks * When sensing voltages, the range of the sensed voltage can be adjusted by adding an external input resistor on the input side. Accuracy - Dynamic performance data XG TCVOUT tr Overall accuracy @ VPN TA = 25C Output ripple voltage @ VPN Thermal drift of VOUT Response time @ 90 % of VPN 1.5 50 0.1 150 % mV %/K s Advantages * * * * * No external power supply is required Good overall accuracy Excellent linearity Low temperature drift Fast response time General data TA TS m Ambient operating temperature Ambient storage temperature Mass - 10 .. + 80 - 15 .. + 80 210 C C g Applications Notes : 1) RIN is not needed whenVP is less than 26.6V. Power rating of R IN should be more than 0.02 x VIN(max) W * DC variable inverter * Railway overhead line voltage measurement * Uninterruptible Power Supplies (UPS) * Battery supplied application 040302/2 www.nanalem.co.jp Dimensions DCVT-25V10 (Unit: mm) 90 81 62 282 142 7 7 Terminal Identification -Vin 1:.....+Vin 1 2 3 GIN 4 5 6 Terminal Block 19 142 19 30 10 20 40 2:.......NC 3:.....-Vin +Vin -Vout 4:....+Vout 4:....Ground 6:.....-Vout +Vout 13 DCVT 25V10 50 Vout 68 2 18 40 J2 4 5 Rin J1 1 Vin1:Sensed Voltage Vin2:Normal Input Voltage Vin1 Vin2 2 Rout 1K 5 Vout Vout:Output Voltage Rin:External Input Resistance to be added 3 6 NANALEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice. |
