SymCom Model 102A is an auto-ranging voltage monitor designed to protect 3-Phase Motors regardless of size. It is used on 190-480VAC, 50 or 60Hz motors to prevent damage caused by incoming power problems. A unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver's output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels. The Model 102A includes advanced single LED diagnostics. Five different light patterns distinguish between faults and normal conditions.

SymCom Model 102LG is a line to ground voltage monitor. It is used on 190-480VAC, 50 to 60Hz motors to prevent damage caused by low voltage conditions from line to ground.

SymCom The Model 201A is an auto-ranging voltage monitor designed to protect 3-phase motors regardless of size. It is used on 190-480VAC, 50 or 60Hz motors to prevent damage caused by incoming power problems.

SymCom Model 201A-AU is the newest, most versatile, plug-in style voltage monitor designed to protect 3-phase motors from damaging power conditions. Its wide operating range combined with UL, cUL and CE compliance enables quick access to domestic and global markets. The Model 201A-AU automatically senses whether it is connected to a 190-240V, 60Hz system, a 440-480V, 60Hz system, or a 380-416V, 50Hz system. An adjustment is provided to set the nominal line voltage from 190-240 or 380-480VAC. Other variable settings include a 1-30 second trip delay, manual or 1-500 second restart delay, and 2-8% voltage unbalance trip point.

SymCom Model 202 is an auto-ranging voltage monitor designed to protect 3-phase motors regardless of size. It is used on 190-480 VAC, 50 or 60Hz motors to prevent damage caused by incoming power problems. The Model 202-RP trips on reverse phase only. It monitors the phase rotation of 3-phase systems. Critical applications include Fan Motors, scroll compressors, grinders, conveyor systems, elevators and escalators. The status light turns green and the relay is activated when rotation is correct.

SymCom Model 250A is an auto-ranging voltage monitor designed to protect 3-phase motors regardless of size. It is used on 190-480VAC, 50 or 60Hz motors to prevent damage caused by incoming power problems.

SymCom Model 350 is a heavy duty voltage monitor. The product should be used when high current relays, dual contacts or 480V controls are used. Since, the Model 350 uses heavy duty relays it comes in fixed voltage range models rather than a dual auto-ranging version like the Model 250. SymCom MotorSaver Model 350-200 comes with a 15A general purpose contact. The Model 350-400 provides a Form C (SPDT) relay rated to switch up to 600V, allowing the use of 480V controls eliminating the need for a Control Power Transformer to step the voltage down to 120-240V. Several two Form C (DPDT) models are also available.

SymCom Model 355 3-phase voltage monitor is perfect for heavy-duty applications that need both protection and simple user-friendly diagnostics. Applications include pump panels, commercial HVAC, oil rigs and others. The Model 355-200 is equipped with a heavy-duty 15A general purpose SPDT relay. The Model 355-400 and 355-600 are equipped with a 470VA @ 600VAC pilot duty SPDT relay. A high voltage (600V) DPDT relay output option is available with the 400V and 600V models.

SymCom Model 455 3-phase voltage monitor combines load and line side monitoring to alert the user of Contactor failure or impending contactor failure. The line side monitoring will protect the motor from damaging line side conditions prior to the motor starting. With other line-load side voltage monitors, the motor must be started before a voltage problem is detected. With the Model 455, the motor is fully protected at all times. The motor will not start when a power problem is present.

The Model 455 automatically senses whether it is connected to a 200V, 300V system or 400V system. An adjustment is provided to set the nominal line voltage from 190-240 or 380-480VAC. Other adjustments include a 2-30 second trip delay, a 2-300 second restart delay (and manual restart), and a voltage unbalance trip point adjustment from 2-8%. Four LEDs indicate the status of the Model 455: run light, undervoltage, overvoltage, and phasing fault. The Model 455 is the only load and line side monitor on the market that does not require a separate power source for its electronics, making it much easier to install.

SymCom Informer MS is a handheld diagnostic tool designed for use with MotorSaver Model 455s equipped with infrared LED transmitters. The Informer MS receives and displays MotorSaver data to assist in monitoring and troubleshooting the system. An auxiliary kit is available which allows the Informer MS to read data from a panelmounted Model 455 without opening the panel door.

Its wide operating range, combined with UL, cUL and CE compliance, enables quick access to domestic and global markets. The Models 460-14 and 460-15 automatically sense whether they are connected to a 190-240V 60Hz system, a 440-480V 60Hz system, or a 380-416V 50Hz system. An adjustment is provided to set the nominal line voltage from 190-240 or 380-480VAC. Motor control is accomplished with one NO contact and one NC contact (Model 460-14) or two NO contacts (Model 460-15).

SymCom Model 601 3-phase voltage monitor is a fully-programmable electronic voltage monitor designed to monitor 3-phase systems. It can be used as a stand-alone product or networked with a RM-1000, RM-2000, PLC, computer or SCADA system. When a harmful condition is detected, the MotorSaver's output relay is deactivated after the specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for the programmed restart delay (RD2).

The following 11 setpoints can be viewed from the 3-digit LED display or from a networked device: low voltage, high voltage, voltage unbalance, low frequency, high frequency, trip delay for voltage/frequency faults, trip delay for single-phase faults, rapid-cycle timer (RD1), restart delay after all faults (RD2), type of restart after all faults (manual or automatic), and RS-485 address. Six parameters can be viewed as the motor is running: L1-L2 voltage, L2-L3 voltage, L1-L3 voltage, average voltage, percent voltage unbalance, and frequency.
