This document is the instruction manual for the HI 96749 Chromium VI Low Range ISM, which introduces the functions, features, and usage methods of the instrument.

R 5 type rotary vane vacuum pumps are a product of Busch, Germany. They are characterized by compact structure, reliable and durable, low maintenance cost, and are suitable for various industrial applications.

This is a water quality meter that can measure pH, EC and ORP values. It comes with two sample cuvettes and caps, a 9V battery and an instruction manual.

The R1224N Series are low supply current CMOS-based PWM/VFM step-down DC/DC controller with an external output transistor. By simply using a power transistor, an inductor, a diode, and a capacitor as external components, a high-efficiency step-down DC/DC converter can be easily configured. The PWM/VFM alternative circuit automatically switches to VFM control in the smaller output current range and provides high efficiency even in the smaller output current range. The version with fixed PWM control and adjustable output voltage with an external resistor is also available. The reset type protection circuit embedded into the device limits output current by repeatedly triggering the soft start circuit when the oscillator maximum duty cycle continues for a predetermined period of time. When the oscillator maximum duty cycle ends, normal operation is resumed automatically. R1224N also includes an under-voltage lockout circuit (UVLO) that stops DC/DC operation and prevents malfunction when the supply voltage falls below the UVLO detect voltage and reduces supply current.

This data sheet mainly introduces the product features, technical specifications, and external dimensions of the Clip IG series industrial measurement amplifiers.

This is an instruction manual that introduces the use of HI96747 Ion Selective Conductivity Meter.

The R1225N Series are CMOS-based PWM step-down DC/DC Converter controllers with low supply current. Each of these ICs consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, a latch-type protection circuit, a PWM/VFM alternative circuit, a chip enable circuit, a phase compensation circuit, and an input voltage detect circuit. Further, protection circuit delay time adjuster circuit, and resistors for voltage detection are included. A low ripple, high efficiency step-down DC/DC converter can be easily composed of this IC with some external components, or a power-transistor, an inductor, a diode and capacitors.

R1245x series 1.2A, 30V step down DC/DC converter

The document describes a system for filling high temperature liquids, including a high-quality case with a blow-out device and a helical bourdon tube measuring system. The system is suitable for alternating load for static processes with slow acting transient pressure.

The R1245x series is a 30V input CMOS-based PWM step-down DC/DC converter with 1.2A* output current. R1245x includes a soft start circuit and latch or fold-back protection circuit. By simply using an inductor, resistors, a diode, and capacitors as external components, a high-efficiency step-down DC/DC converter can be easily configured. Due to current mode PWM control, the R1245x provides a fast response and high efficiency. Ceramic output capacitors can be used. Compared with R1240x, R1245x has a lot of variation of oscillator frequency and can select 330kHz. In case of 330kHz, R1245x can set VOUT lower than R1240x. The oscillator maximum duty cycle (Min.) of R1245x is larger than R1240x, so it is suitable for low dropout voltage situation. The noise characteristic has been improved rather than R1240x, and voltage accuracy is also improved. In addition to HSOP-8E package can be selected, so R1245S is suitable for high power dissipation case.

The R1243x series is a CMOS-based Step-Down DC/DC Converter with internal Nch high side Tr. (0.175Ω), which can provide the maximum 2A output current. The IC consists of an Oscillator, a PWM control circuit, a Reference Voltage unit, an Error amplifier, phase compensation circuits, a slope circuit, a soft start circuit, protection circuits, internal voltage regulators, and a switch for bootstrap circuit. The R1243x Series can make up a Step-Down DC/DC Converter with the following external components: an inductor, resistors, a diode, and capacitors. The R1243x series are current mode operating type DC/DC converter which does not require external current sense resistor, and it works high speed response time, high efficiency and compatible with ceramic capacitors. There are two types for the oscillator frequency. A/B version's frequency is fixed 1000kHz, and C/D version's frequency is fixed 330kHz.As a protection function, it has cycle by cycle peak current limit function, short protection function, thermal shutdown function and UVLO. There are two types for short protection, A/C version has latch protection function with 2ms delay time, and B/D version has fold back protection function that keep operating at short condition with lower operating frequency and limiting the Lx current. The R1243 Series has the built-in soft start time (Typ. 0.4ms). In addition to this, the soft start time is adjustable by controller's I/O port.
