Landis+Gyr Chapter 1 - Product Overview
Gridstream SCADA/DA S4SBR 98-1138 Rev AD 7
Pin 1 (VIN)
This pin must be supplied with DC voltage between 4.0 and 7.0 VDC with 5.0 VDC considered
nominal.
The input voltage is linearly regulated on the board. While the linear regulation can remove some
noise, Power Supply Rejection Ratio (PSRR) varies with frequency. If the power source is
particularly noisy, filtering may be required. Landis+Gyr engineering can assist in defining radio
tests to determine if power supply noise is affecting radio performance.
The input voltage must be maintained between 4.0 VDC and 7.0 VDC during operation. The on-
board electronics include fast-acting reset circuitry. If the voltage drops below 4.0 VDC, even
transiently, the system will reboot once the voltage returns to normal range. If the voltage rises above
7.0 VDC, even transiently, the voltage-sensitive components could be damaged.
Upon power up, the on-board processor and voltage regulator requires the supply voltage to have a
minimum of 0.05 V/msec slew rate - which implies rising from a logic 0 to a logic 1 in no less than
66 msec. Power consumption during normal receive mode is typically 41 mA. Current consumption
during 100 mW transmit mode is 250 mA, 440 mA during 450 mW transmit mode, and 520 mA
during 600 mW transmit mode.
During the first 30 minutes after initial power-on or after an extended outage, the on-board super-
capacitor will be charging. During this time, the total input current to the device will increase by 80
mA. SeeTable 1 - 1, "Series 4 Gridstream S4SBR General Electrical Specifications," for additional
details.
The Gridstream S4SBR uses a frequency-hopping sequence transmission and, while typically rare,
transmissions can be as long as 400 mS in duration, and can theoretically sustain at a 45% duty cycle
on a single channel.
