DC 6~80V Relay Switch Controller

A30-U1

Features:
Digital display DC voltage detection, control the relay output.
DC 6~80V relay interface board with 2 buttons for easy operation.
With clear LED display, convenient to check the value.
Adjustable Voltage Detection Range: DC 0~99.9V.
When the measured voltage is lower than the lower limit or higher than upper limit value, the relay works.
Can be used for voltage detection switch, battery over/under voltage protector or discharge meter.
Comes with a cover for protection.

Specifications:
Material: PCB + ABS
Working Voltage: DC 6~80V

Voltage Detection Range: DC 0~99.9V
Error: +/-0.1V
Working Current: 8mA/24V(relay open, LED displays OFF about 4mA/24V); 58mA/24V(relay closed)
A set of transformations(normally open/normally close, NO/NC)
Contact Load: NO: 30A/250V AC or 30A/30V DC; NC :20A/250V AC or 20A/30V DC

Attention: Because high voltage DC electric arc damages relay contact,
so the electric load above DC60V load current is less than 10A.
Contact Resistance: ≤100mΩ(1A 6VDC)
Mechanical Durability: 10 millions Electricity durability: >100,000 (20A~250VAC)
Operating Temperature: -40~85°C
Item Size: 9.4 * 5.2 * 3cm / 3.7 * 2.05 * 1.18in
Package Size: 9.5 * 6 * 3cm / 3.74 * 2.36 * 1.18in
Package Weight: 85g / 3oz

Package List:
1 * Relay Switch Controller

A30-U3

Features:
Operating
power is DC 6 to 80V, contact load is 30A, 250V AC or 30V DC. High
quality voltage monitoring relay is durable, and features fast reaction
times, making it more efficient.
Supports on delay and off delay mode, the delay time can be adjusted from 0s to 999s.
Provides
4 operating modes: P-1, relay close delay time and display off setting;
P-2, voltage control timer A (delay on); P-3, voltage control timer B
(delay off); and P-4, voltage range control.
It has a voltage
detection channel, a set of relay switch output(normally open and
normally close), the time relay can be controlled by voltage detection
to achieve a variety of functions.
Can be used in voltage monitoring, charging and discharging control, overvoltage and under voltage protection and other fields.

Parameters:
A Set of Conversion: normally open and normally close

Contact Load:
NO: 30A/250V AC or 30A/30V DC
NC: 20A/250V AC or 20A/30V DC
*Attention:
because high voltage DC electric arc damages relay contact, so the
electric load above DC 60V load current is less than 10A.
Contact Resistance: ≤ 100mΩ (1A, 6V DC)
Mechanical Durability: 10 millions
Electricity Durability: ＞ 100,000 (10A to 250V AC)
Set display off, the minimum current value is 4mA/24V(relay open).
The settings automatically saves after power off.

Specifications:
Material: ABS
Colour: Blue
Output Timer Range: 0 to 999 seconds (when the voltage reaches the set value, relay will delay to open or close)
Detection Sampling Delay: 0.1 to 0.9 seconds (detection sensitivity)
Voltage Detect Range: DC 0 to 99.9V, error: ±0.1V
Voltage Upper and Lower Limit Adjustable: DC 0 to 99.9V
Operating Power: DC 6 to 80V (60V battery at maximum)
Item Size: 9.4*5.2*3cm / 3.7*2.04*1.18in
Package Size: 9.5*6*3cm / 3.74*2.36*1.18in
Package Weight: 92g / 3.24oz

Packing List:
1 * Voltage Relay
