Orion-TR Smart Non-Isolated DC-DC Converter - 24 VDC to 24 VDC - 400W - 17AMPThe Orion-Tr Smart DC-DC charger is a professional DC-to-DC adaptive 3-stage charger with built-in Bluetooth.Bluetooth Smart Enabled:Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, change settings, and update the charger when new software features become available.Instant Readout: The VictronConnect App can display key data, including warnings and alarms, on the device list page without the need to connect to the product.  Fully Programmable:Battery charge algorithm (configurable) or fixed output. Smart alternator compatibility: engine running detection mechanism.  Adaptive 3-Stage Charge Algorithm: Bulk – Absorption – Float:For lead-acid batteries, it is important that during shallow discharges the absorption time is kept short to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely recharged.For lithium batteries, the absorption time is fixed (the default is 2 hours).Alternatively, a fixed output voltage can be chosen.  Remote On/Off:A remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two-pole connector can be switched to battery minus (or the chassis of a vehicle, for example).  All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output Current:An unlimited number of units can be connected in parallel.High Temperature Protected:The output current will reduce at high ambient temperatures.  IP43 Protection:When installed with the screw terminals oriented downward.  Screw Terminals:No special tools are needed for installation.  Input fuse (not replaceable) Specifications:Input Voltage Range: 20-35 VUnder Voltage Shut Down: 14 VUnder Voltage Restart: 15 VNominal Output Voltage: 24.2 VOutput Voltage Adjust Range: 20-30 VOutput Voltage Tolerance: +/- 0,2 VOutput Noise: 2 mV rmsCont.
