OVERVIEW

This quick start guide is for those users who are

not very familiar with the usage of this instrument.

It provides a way of quickly understanding this

device. For details about functions such as system

settings, saving & recalling features and remote

control instructions, please refer to the PPH-1503D

user manual.

This quick start guide contains the following content:

Introduction

Introduces the instrument panels and main

features.

Operation

Describes the display interface and the functions

of the interface keys.

Overview

The PPH-1503D is a high-precision, compact, dual

output, multifunction, programmable DC power

supply with flexible operating configurations. In

addition to the basic power supply functionality,

it is also able to measure pulse current, the

average current over long periods of time and

other functions such as battery simulation.

The PPH-1503D is designed for testing the power

consumption of battery powered wireless

communication devices (e.g. cell phones). Such

devices often have large load variations within a

short time span. The high precision power supply

has excellent voltage stability during pulsed loads

and is capable of simultaneously measuring the

pulse current, even for very short pulses. In

allowing it to simulate the characteristics of a

discharged rechargeable battery for testing

chargers and charge control circuits.

Parameter

Description

CH1 and CH2 operate as a basic power supply

with the ability to simultaneously display V/I

settings and readback values. The output from

CH1 can be toggled between the front and rear

outputs using the Rear key. When the Rear key is

lit, it indicates that the rear panel output is

activated and that the front panel output is off.

Both outputs can’t be activated at the same time.

IntRate

from the number of power line

cycles.

The setting range is:

*PLC stands for power line cycles.

AverRead

Readback refresh rate. This will

display the average number count.

CurrRange

off when the current limit has been

reached.

See page 27 for details on the Limit

Relay and Trip Relay settings.

DVM

Description

The PPH-1503D has a separate digital voltmeter

with a measurement range of 0~+20VDC.

Note: DVM and CH2 have a common ground

design. So when using the DVM- terminal, it can’t be

shorted with the negative output of CH2. In addition,

when using the voltage meter, the power supply must

be properly grounded.

Parameter

Description

Intrate

Sets the reading rate of DVM

measurements based on the number

of PLCs. The setting range is:

0.1PLC to 10.

1PLC=16.7ms(60Hz) /20ms(50Hz).

*PLC stands for Power Line Cycle

AverRead

The number of samples used to

calculate the average.

Normally the unit will display

measurement results onto the screen

as soon as they are captured.

However when more stable results

are needed, averaging can be used.

The AverRead function collects

several samples of data and then

performs an averaging operation on

the data before displaying the

averaged result on the screen.

affect the operation of the power supply. The

output can be turned on or off by pressing the

Output button.

Pulse Current Measurement

Description

Changes in the load current allow us to measure

the pulse current.

There are three ways that pulse current can be

measured:

1. Measuring the peak current over a single cycle

(High Measurement).

2. Measuring the trough current over a single

cycle (Low Measurement).

3. Measuring the average current over a single

cycle (Average Measurement).

The high and average measurements are

triggered by the rising edge of the pulse current

are performed for the time specified for the

measurement.

Low measurement is triggered by the falling edge

of the pulse current.

Note: Pulse current measurement is only valid

up to 5A (CH1) and 1.5A (CH2).

Parameter
