[mini-UPS] Sockets and Indication Elements

State Terminal Block

A state terminal block is a set of logic outputs (IO lines), which are used for a device status signalling.

A terminal 1 is an output “normal”. Its logic level “1” (no less than 2.4V) indicates an availability of an input voltage, a battery is charging. A level “0” (no more than 0.4 V) indicates a lack of an input voltage, a battery is discharging.

A terminal is an output “critical level”. “1” is a normal battery level, “0” - a battery is critically discharged, it is issued 3-6 minutes before a device shutdown.

A terminal 3 – GND

  

DC/BAT LED

DC/BAT LED. A green light means having a voltage on an input. A red one means there is no voltage on input, a battery is discharging. 

OUTPUT VOLTAGE Block

An OUTPUT VOLTAGE block, which is a UPS output, consists of 5V/GND, 12V/GND terminals and a 5V – 12V switch.

A switch 5V – 12V is used for turning on/off a 5V -> 12V transformation.

A terminal 5V is an output of UPS+5V. There is always a voltage on this terminal during a device operation regardless a position of a 5V – 12V switch.

A terminal 12V is an output of UPS+12V. There is a voltage on this terminal only when a 5V-12V switch is at a 12V position.

ImportantKeep a switch 5V – 12V in a position 5V, if you do not plan to use a terminal 12V. This will increase a battery life time.

DC INPUT Block

A DC INPUT block (picture 8), which is an UPS input, consists of a socket DJK02 for 2.1 mm dowel and +DC/GND terminals.

A DJK02 socket for a 2.1 mm dowel is used to power a mini-UPS device with the help of a power supply unit, for example, Power adaptor NetPing.

+DC/GND terminals are used to power a mini-UPS device with the help of other Netping devices, for example, Uniping v3, Uniping Server Solution v3/SMS. For these purposes, a 12V relay, built into a body of devices, is used.

ImportantIt is prohibited to power a mini-UPS device simultaneously from two different power supply units through the socket DJK02 and the terminals +DC/GND.

BAT Switch

A BAT switch is used to unplug a battery before a transportation or a long-term storage of a device. A device supplies a voltage to outputs, when there is an external power supply, even if a switch is in an OFF position.

Important!  Switching to the OFF position puts a device into a standby power mode, when there is no external power supply. A device exits this mode when a power is supplied. Switching to the ON position will not put a device out of a standby power mode. In a standby mode a voltage is not supplied to UPS outputs.
