Note highlights important information on using the product. ESD Protection Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits. Vaisala products are adequately protected against ESD for their intended use. However, it is possible to damage the product by delivering electrostatic discharges when touching, removing, or inserting any objects inside the equipment housing. -
Page 7: Warranty
- Always hold the boards by the edges and avoid touching the component contacts. Warranty For certain products Vaisala normally gives a limited one year warranty. Please observe that any such warranty may not be valid in case of damage due to normal wear and tear, exceptional operating conditions, negligent handling or installation, or unauthorized modifications. - Page 8 User's Guide _______________________________________________________________________ This page intentionally left blank. 6 _____________________________________________________________________M210374en-A...

Page 9: Chapter 2 Product Overview
The input voltage for the QBR101 can be taken from a 15 V- 30 VDC source. This may be, for example, an off-line SMPS or a solar panel. -
Page 10: Figure 1 Functional Block Diagram Of Qbr101
In normal 12 V operation the input power (to X1/1 and 2) is taken from an off-line SMPS with a 15.5 to 16 V output voltage. Inside the QBR101 the input voltage is applied both to the Battery Charger and via the Voltage Drop Circuit to the output terminals DCout (X2/1) and DCout/Switch (X2/5). -
Page 11: Charger
Chapter 2 ___________________________________________________________ Product Overview Inside the QBR101 the Solar Panel inputs (X1/5 and 6) are applied only to the Battery Charger, i.e. they have no straight connection to the DCout terminals. This is because the 12 V solar panels may present output voltage levels as high as 28 V, not suitable for all equipment normally connected to the DCout terminals. - Page 12 DCout/Switch output. A deep-discharged battery condition will naturally override this condition and turn the output off. The QBR101 has a test terminal Vb Meas for the datalogger to measure the battery voltage. The output level of Vb Meas is between 0 and 2 V.

User's Guide _______________________________________________________________________ Table 3 Output Connector X2 Pin No Terminal Name Notes Dcout Output terminal for straight DC-output. This output is always live, when DCin+ voltage is connected or when charge is left in the battery. Ground terminal for DCout and DCout/Switch outputs. -
Page 15: Jumpers And Leds
Jumpers for Charge Current Limit The battery charging current limit can be adjusted in 0.5 A steps with the three jumpers J1 - J3 on the QBR101's front panel. The adjustment is normally made according to the battery capacity. For example, a suitable charging limit for a 12 Ah lead-acid battery would be 1.0 to... -
Page 16: Mechanical Installation
Mechanical Installation The QBR101 can be installed to 35 mm DIN-rail using rail clip on the rear. Alternatively it can be mounted to a wall or equivalent surface with M3 screws on the bottom. The maximum allowable length of the screw threads is 6 mm. -
