RF-LPS
The RF-LPS is a low power RF controlled switch which draws only 90µA! Primarily intended as a remote
controlled device for battery saving applications, the RF-LPS is designed to remotely connect and dis-
connect the (battery) power supply to a connected device. The RF-LPS is used in conjunction with the
2CH-REML two channel RF remote transmitter. Pressing the GREEN button on the remote will cause
the RF-LPS to pass the external (battery) power supply of the connected device, turning it ON. Pressing
the RED button interrupts the external (battery) power to the connected device, turning it OFF. The RF-
LPS is constantly powered by two internal Lithium-Ion batteries lasting up to sixteen months. The RF-
LPS is ideal as a power saving (retrofit) interface for applications that are usually constantly powered, but
are not being used for continuous duty.
Features
• Low current consumption (typically 90µA)
• Long battery life: continuous operation up to
16 months off internal batteries
• Switches any supply from 5V
• Can switch external loads up to 400mA
• For higher currents, a relay may be used to
switch the power supply
• Simple series connection between load
power supply and load device
• Works in conjunction with the 2CH-REML
handheld RF remote radio transmitter
• Operates on 433.92MHz
• Receiver has -94dBm sensitivity
• Open Field Range of up to 400 feet
• 8 bit selectable address
Without the RF-LPS, the remote device is constantly on, drawing maximum current

- Page 1 RF-LPS *90µA* Low Power RF Controlled Switch The RF-LPS is a low power RF controlled switch which draws only 90µA! Primarily intended as a remote controlled device for battery saving applications, the RF-LPS is designed to remotely connect and dis- connect the (battery) power supply to a connected device.
- Page 2 Simply connect the external power supply to the ‘Supply In’ jack on the RF-LPS and plug the out- put of the RF-LPS in to the supply input of the desired load or device. If the device being switched through the RF-LPS draws more than 400mA, the RF-LPS output can be used to drive a relay whose contacts can switch the supply to the load device.
- Page 3 Switch position 9 must always be set to OFF. (default position). This is important for correct operation. Switch 10 position will affect the output state of D3 pin header on the RF-LPS. DIP switch 10 in the OFF position (default position) will always result in a HIGH state on pin D3 regard- less of which button is keyed on the transmitter.
