Battery Charging

Our range of ampere hour meter – IM2501 monitors the current flow through the circuit and the charge through the battery which is very important for battery charging or discharging applications. Some of the advantages of this model are:

• Shunt value can be programmed by the user, so suitable with any circuit
• Provided with one relay output in order to warn the user whether the required charge has been delivered or just to directly cut off the rectifier

Here are some of the features of the product:

• 8 key membrane keypad
• One set point with relay output rated 230 V / 5 A (resistive)
• Ampere Hour / Ampere Minute selection
• Shunt value programmable at 75mV
• External Reset facility
• Size 96x96 mm depth 150 mm

We offer ampere hour meter with totaliser under the model no. IM2502. This model is a step ahead of the IM2501 model and it provides a totaliser display along with ampere hour/ ampere minute display. Also, all the features of the earlier models are retained. Some of these features are mentioned below:

• Membrane keypad for programming
• One set point with relay output rated 230 V / 5 A (resistive)
• Ampere Hour / Ampere Minute selection
• Shunt value programmable at 75mV
• External Reset facility

We offer IM2506 model which provides 6 digit display as compare to IM2501 ampere hour meter which ahs 4 digit display. This model can be used with any circuit as the shunt valve can be programmed by the user. The equipment is provided with one relay output to alert the user when the sufficient charge has been delivered. It is also used to directly cut off the rectifier. Some of the features of this model are as follows:

• Range 0-999999 Ah
• Least count 0.1 Ah for shunt value less 25A
• Accuracy +/-1% of current range
• Shunt Input 0-75 mV
• Shunt value programmable 1 to 9999 amperes
• Current (ampere) display with keypress
• Battery back up to retain count in case of power failure

We also design and produce highly efficient IM2501k KAH meters which are widely used in applications related to submarine and telecom. In these sectors, huge battery systems are used and the current flow is in kilo amperes. This model offered by us is capable of providing current and ampere hour display directly in kilo ampere hours. Following are some of the features of the product:

• Shunt value programmable
• Relay output for rectifier control with one set point
• Battery back up to store reading in case of power failure

We are engaged in providing IM2508 ampere hour profile meter which is a programmable step profile type device. During the battery formation process, the battery must be charged at different ampere hour capacity in steps. Some of the special features of the product include short circuit monitoring, starting current control and bar forming timer. Other features of this model are listed below:

• 4 plus 6 digit display for AH meter and step programming
• Three relay outputs for C1 / C2 and short circuit
• Analog voltage output for current control of external rectifier
• Back up to retain count and status in case of power failure
• Programmable bar charge / short circuit timings
• Optional Modbus Serial interface
• Shunt value programmable at 75 / 100 / 60 mV

While the charging process, when a battery is sufficiently charge, the current flow drops to a lower level. At this juncture, the battery must be disconnected from the source of power. Our high quality IM2512 model is capable of operating in two different modes. The operational details are provided below:

• The relay operates when ampere hour value reaches the set point, this is in accordance to a preset
• Has current limit value with a delay timer: as the current drops below a certain limit value and remains for more than delay time, the relay will operate
• Relay can be used to cut off the battery
• The model has a totaliser similar to IM2502

Some of the features of the product are:

• 4 plus 6 digit LED display for showing current flowing in circuit, ampere hour count and totaliser count on key selection
• Shunt value programmable from keyboard
• Floating decimal point depending on shunt value programmed.
• Ampere Hour / Ampere Minute display selectable from keyboard
• One programmable preset count with relay output to control charging rectifier
• Battery back up to retain the count in case of power failure
